I think you're right. A lot more people would let Windows 11 auto-install if Microsoft wasn't so picky about processors in particular. I know I have an i7-7700HQ machine I'd put 11 on if the process was seamless. I don't think Secure Boot or TPM issues are quite as prevalent compared to arbitrary hardware cutoffs. I haven't seen a clear explanation as to why Microsoft drew the line on processor compatibility where they did.
However, I don't think Windows 11 is suited to a content creation or gaming machines. 11 reminds me of Vista and 8 -- lots of questionable UI choices that get in the way or waste space. Too many clicks to get to hidden things. The lack of small taskbar is a dealbreaker in particular.
IMO, I think MS is taking notes from Apple on this. Windows 10 works on such a wide variety of hardware that the experience isn't uniform. I feel like they are trying to dispel the myths that the OS itself if to blame by setting newer more modern standards by which the new OS environment can run on such to eliminate that disparity.
