I’m sure you found your attempt to belittle amusing but there is far more to it than just tyre pressure!
Tyres that supposedly worked 12 months ago on hookless rims now don’t or do with some internal widths but not others. I cannot just walk into a shop and buy a tyre and throw it on the rim like I can with the wheels I own now I have to consult the wheel manufacturer data and the tyre manufacturer data and adjust pressure not for road conditions but to stop the tyre unseating. If I fix a flat with Co2 out on the road how do I know I haven’t exceeded the safe limit for pressure?
It’s almost a bike tyre version of the Manchester Triage System when something goes wrong the system is amended.
If the pro Peleton are having problems with their average weight being less than <70kg and their bikes set up by professional mechanics perhaps hookless rims are not a very good idea for the mass market? Or maybe they are just not there yet? Either way I think I will pass for now as I’m not currently being forced by the industry to buy them.
if you don't want to buy the wheels don't buy the wheels. the number of companies making hookless road rims is still in the vast minority. just, based on my experience the issue you describe isn't an issue. i've been riding these wheel and tire systems for 4 years, many different combos, and i haven't faced any issues you describe. there isn't anything anybody really describes here that we didn't face with road tubeless.
in the very beginning of this i established 3 rules for myself: 1) i will not ride this kind of system with any tire narrower than 28c; 2) i will maintain a delta between inner bead width and nominal tire size of between 5mm and 7mm; 3) i will stick to tire and wheel brands i trust.
now, in point of fact, these aren't my private rules i've established for hookless systems; they're for all road tubeless systems i ride, hooked or hookless. so for me no problem. in the beginning of all of this people complained that hookless are not safely usable with 25c tires. fine (i said), i'm not inconvenienced, i only run 28c and up. "but then you can't run them on the fastest tire width!" to which i said, "let's see if 25c remains the chosen tire width." so i'm happy as a clam because the world has turned toward my preferences, techwise.
fortunately for you, you have plenty of hooked rim options. but you are still the beneficiary of hookless i think, because certain tire brands that made beads too stretchable for hookless are having to pay a lot of attention to their beads, and that makes their tires better for your use (their beads too stretchable for safe use on hooked rims as well).
