I will not post a link to it for privacy reasons, but I wrote an article on this the day before the original M1 was announced warning of this situation. Apples move to their own chipset meant that any attempts at maintaining compatibility would always end up behind the curve.

I am surprised that Apple manage to keep their chips constantly changing as much as they do between generations. Most others seem to be on the 'same but more' path nowadays but Apple is still shifting the baseline almost yearly.

The real issue will come if they lock down the boot loader.
