How ironic that you're the one pushing your opinions as consensus, and what's more, strawmanning.
I am going back to "wait for it to fly", but I have to push back on the "uselessness" of a "low supersonic" bomber. You're injecting NATO perspectives when there's already the GJ-X in development, and you're strawmanning by claiming I'm suggesting a low supersonic bomber, when I'm seeing Mach 1.3 as a minimum.
I am suggesting, rather, sprint to Mach 1.5 or 1.8 before dropping the hypersonic, injecting additional speed, and the capability to egress safely, as much as older Backfires and Tu-160 could.
The entire issue is that what you're expecting and pushing for is two things, first, an aircraft in the NATO mode, which expects air superiority and wants volume of fire, second, a Chinese B-2 or B-21 knockoff, which will likely have worse stealth than a B-2 or B-21, especially since we're seeing departures from the flying wing geometry in all initial sketches.
Then there's the fact that the US is working on counter stealth satellites, as much as the Chinese have, so that the H-20's stealth is probably irrelevant.
If the Chinese are going for 5th or 5.5th generation bombers, analogues to the B-2 or B-21, they already are working on an unmanned version. If they want an el cheapo H-20, fine, it's easy for the West to deal with (which is what you want). If they are going to produce a 6th generation very-large-aircraft, it's a whole different ball game.
At the very least, it'd explain why the H-20 seems to be so delayed, because requirements changed mid-project.
Just wait for it to launch, and let the aircraft do the talking
Counter stealth is evolving and there isn't anything like a silver bullet solution. Photonic/quantum radar are experimental and far from providing militarily useful tracking and firing solutions. Maybe China has finally fielded early generation but if it were certainly effective, we'd be seeing some scrambling from behind the scenes and hints being dropped by the US that China is making this mad dash to upgrade its armed forces with this new piece of technology.
Right now, the real concern for stealth being overcome by counter stealth does not kill programs like H-20 and B-21.
Counter stealth satellites aren't making stealth fighters non-effective. A satellite doesn't guide your A2A missiles. Knowing a bit more about where the general presence of a stealth aircraft is, doesn't entirely remove that aircraft's utility. It might be a bit more effective against unescorted bombers but with VLO and even ULO fighters and UADFs escorting H-20, I don't see how a GJ-x is an alternative to the H-20. It's been discussed before but a strategic, manned ULO bomber is not a medium range, unmanned ULO bomber you would not be strapping nukes to because 1. communication and controls can potentially be disrupted and 2. you don't really have nuclear targets at those medium ranges.
