It seems like this is a bug, apple went through the trouble to allow something like asahi to be possible in the first place. I doubt they're purposely trying to break it.
Apple designed a bootloader for Apple Silicon Macs that allows you to run an unsigned OS without degrading security when you boot into MacOS. This wasn't an accident.

Macs have always allowed you to run another OS.
iDevices have always had a locked bootloader.
People shouldn't confuse the two.
