So it's the model that determines what OS version can be installed. Not the version it comes with, and the version of recovery partition, like I said. But we agree that rolling back is seriously limited.
Anecdote: My closest encounter with this, and part of the reason I decided to stay w/Catalina on Intel, was two weeks with a M1 Mini earlier this year, and Carbon Copy Cloner could no longer create bootable backups because of this change with Big Sur. They might have solved that now, or found a workaround.
