The easy path on M1 would have been to lock everything down. Use the same iBoot phones use, the same kernel configuration, and call it a day. It takes a lot of engineering work to make more permissive security modes work. To re-architect booting. To make external drive booting work. To make developing kernel extensions on production systems work. To allow signing your own boot blob. Work that 99% of users don't even understand let alone care about. If that isn't enough evidence then nothing ever will be.
