That's called incremental progres. Block 1 & 2 was not good, but pakistan walked the ladder incrementally to get Block 3 which have an AESA radar and the ability to use PL-12 & PL-15. And in comparison, the peak of egypt air force is Mig-29m have missiles that have theoritacal range comparable with PL-12 but doesn't have AESA radar, Rafale has the radar but only with MICA for ~80km range. So JF-17 block 3 beats both.
Egypt could have got the ability to participate in manufuctring a 4gen aircraft, they didn't historically make or even participate in 1nd,2nd or 3rd Gen aircraft. This deal was a game changer for the industralization for the middle east & Africa
and Egypt could field it in high number 100-200 aircraft, and can diverse their arsenal with some turkish armaments & sub components for instance.
Egypt can use to enlarge their base to maintain and use Chinese aircraft, and ease the integration of high end aircraft like J-35AE.
If something happen for either of them, the other can tap its industry and help them.
Pakistan & Egypt can make joint excersice for the network of countries who used it or are interested in it...etc
It's a fighter that provides a base for all countries to protect their Airspace with minimum economic cost with a non-western partner that's reliable which is China.
Any talk about "it didn't meet this requirement" or "It's worse than X aircraft" only talk about individual platform specs, but fails in strategy and defence economics. And even then, they avoid mentioning the fact that their "precious" fighters like F-16 can't field long range weapons that reach 100km because of US interference -- let alone beyond that range.

Despite Turkish propaganda suggesting Egypt is invited to participate in the KAAN aircraft project, I personally believe it will not reach completion. Even Egypt's manufacturing of parts of the Rafale's airframe and M88 engine components, even to a greater extent than publicly announced, is unlikely. However, the real cooperation will most likely be with China, not just in terms of purchasing but also in terms of licensed production. Information about this is expected to emerge around 2027, primarily concerning guarantees of actual implementation.

Egypt's priority now is the production of munitions and missiles for fighter jets and UCAF aircraft, as well as expanding its UCAF program. This is also being pursued extensively with China, and partially with Turkey, Pakistan, Belarus, Serbia, and even the UAE, which serves as a front for Egyptian projects.
