Maybe instead Microsoft could allow Windows 11 to install and run on machines that are otherwise capable and just flash red screens at you all the time where otherwise ads would show up that constantly nag that "THIS COMPUTER IS FUCKING INSECURE!" or something. It would be equally as annoying but I'm sure running latest Windows 11 but with TPM 1.0 instead of TPM 2.0 will be more secure than running Windows 10 without bug fixes and security patches.
(But my understanding is there were other things like bumping minimum supported instruction sets that happened to mismatch a few CPUs that support the newer instruction sets but were shipped with chipsets using the older TPM)
We want to delete the fallback code paths... You'll just get failures from bitlocker instead of install failures, or windows hello failures, or ...
