I'm actually not sure about the wheelchocks thing.

It depends entirely on what the width of the wheels between J-XY/35 is versus J-15, and whether the existing arrangement can accommodate it.

For example, Kuznetsov during its Syria deployment to my knowledge operated both Su-33 and Mig-29K
That's indeed true.

However, Kuznetsov's wheelchocks are able to handle both the Su-33 and MiG-29K by being physically wider:

The wheelchocks on Kuznetsov have been designed such that the outer halves of the wheelchocks are used for the Su-33, while the inner halves of the wheelchocks are used for the MiG-29K.

Meanwhile, the wheelchocks on Liaoning and Shandong are visibly narrower than those on the Kuznetsov:

@sugar_wsnbn's reasoning being that the J-15 and the J-35 have a 3-metre difference in width, such that "so naturally, the position of the landing gear (i.e. the spacing in between the rear landing gears of both fighters) is also different".

However, I won't rule out the possibility that the J-35 designers at Shenyang might have designed the rear undercarriages of the J-35 to have similar spacings in between those wheels as those on the J-15 - Either that, or wider wheelchocks that can accommodate both the J-15s and J-35s have already been installed on Liaoning during her recent MLU.

Why do the wheel locks need to have gaps in them?

It's just a way to enable them to fit into the deck flush while also being able to act as wheelchocks, while minimizing the impediment to the structural integrity of either.

That's indeed true.

That's a reasonable case being made in regards to kuznetsov's wheelchocks, though I have a sneaking suspicion that we probably aren't going to get very high quality imagery that can definitively confirm if there are any modifications to CV-16/17's wheelchocks for a while -- I wouldn't be too surprised if the first confirmation we get of J-XY/35 being compatible with CV-16/17 is official imagery of it operating from one of the STOBARs.

Or putting it another way, I wouldn't hold out too much hope for measuring wheelchock width as something to watch out for, for our purposes (especially if J-XY/35 has a similar wheeltrack/width to J-15, which can't be ruled out -- which even though J-XY/35 is in a different weight class and has different dimensions to J-15, it also is of a different design and generation as well).

... and if we do get near term clear imagery of CV-16/17's wheelchocks and they look unmodified from their existing dimensions, that also does not necessarily demonstrate anything.

Some tidbits from pop3 in conjunction with the recent spotting of a J-35 mockup on Liaoning.

早在2004年的048工程规划,也就是上报中共中央政治局的《中国发展航空母舰的规划论证报告》时,就明确提出,瓦良格舰用研仿的歼15作为舰载固定翼作战飞机,后续弹射型航母,要发展四代机为舰载机。
在进行弹射型航母研制时,舰载机的发展,也就是四代舰载机的调研、协调和可行性工作一直在进行。
当时船总的设想是以歼20飞机为原型,发展四代舰载机。
当时成都和沈阳都在发展研制四代机,业内也知道这个情况,我还曾看过沈阳四代机的介绍。
后来因为种种原因,军方选择了沈阳的四代机方案。
这里必须要说一句,这里面并没有什么“小利益集团”之类的不实猜测,也没有人敢在这些涉及国家重大工程上动手脚,成千上万双眼睛盯着呢。
航母三号舰上四代机已成定局,但有可能在前期是混搭的状态,也就是歼15与四代机同时出现。
凡事都有前伸后延,这也是符合人民海军一贯所要求的“实时改进”原则的。
在辽宁舰上进行四代机的测试也就不足为奇了,四代机早晚会取代三代机。
最后说一点,辽宁舰这次返厂维修,可并非简单的维修,各种升级、替换的工作量极大。
这也符合人民海军上述的原则,在下在不经意时也听到点,但这些内容属于绝不能说的范畴。
其实,此类制度在人民海军舰艇的坞修、小修、中修时,都是如此执行的。

Roughly translated:
As early as the Project 048 in 2004, which was the "Planning Demonstration Report for the Development of China's Aircraft Carriers" submitted to the Political Bureau of the CPC Central Committee, it was clearly stated that the Varyag would use the J-15 as a carrier-based fixed-wing combat aircraft. For subsequent catapult-type aircraft carriers, 5th-generation aircraft must be developed as carrier-based aircraft.
During the development of CATOBAR aircraft carriers, the development of carrier-based aircraft, that is, the research, coordination and feasibility work of fourth-generation carrier-based aircraft have been ongoing as well.
At that time, the chief ship designer/manager’s idea was to use the J-20 aircraft as a prototype to develop a 5th-gen carrier-based fighter.
Simultaneously, both Chengdu and Shenyang were developing 5th-gen fighter, and the industry was aware of this situation. I had also seen an introduction to Shenyang’s 5th-gen fighter.
Later, due to various reasons, the military chose Shenyang's 5th-gen fighter plan (for adaptation as a carrier-based fighter).
It must be said here that there are no false speculations such as "small interest groups" here, and no one dares to interfere with these major national projects. Tens of thousands of pairs of eyes are watching (the selection process).
It is a foregone conclusion that the 5th-gen fighter will be installed on the 3rd aircraft carrier (Fujian), but it is possible that the aircraft composition will be mixed in the early stage, that is, the J-15 and the 5th-gen fighter will appear at the same time.
Everything has its way forward and back, which is also in line with the principle of "real-time improvement" that the PLAN has always demanded.
It is not surprising that the 5th-gen fighter is being tested on Liaoning. Sooner or later, the 5th-gen fighter will replace the 4th-gen fighter (on aircraft carriers).
Last but not least, Liaoning's return to the (Dalian) shipyard for maintenance and is not for a mere simple repair-and-upkeep. The amount of workload in conducting various upgrades and replacements (on the ship) is immense.
This is also in line with the above-mentioned principles of the People's Navy. I may hear it inadvertently, but these contents belong to the category that must not be said.
In fact, this type of system is implemented in this way during dock repair, minor repair, and medium repair of the People's Navy ships.

Two facts:
1. Liaoning's return to Dalian Shipyard since late last year is most definitely a mid-life upgrade (MLU) of some sorts.
2. The choice to adopt J-35 for carrier-based operations over the J-20 has been clean-cut since the very beginning. I think we should put the so-called "J-35 is a bad plane for a carrier-based fighter, the PLAN should've go with J-20 instead" debate to rest.

pop3 also said one thing
Development of short vertical take-off and landing aircraft
The two major airlines in the North and the South are working hard to develop short-range/vertical take-off and landing models, let's see.

Well, if the decision for the carrier-based operation has been clean-cut since the very beginning, why J-35 progress is so slow or rather started so late?
And the funding for FC-31 is from SAC not PLAN and it's a export project from the get go?
A lots of contradiction facts here.
