You can't even use Linux on Intel Macs properly, no chance it'll work on the M1 anytime soon. The kernel might boot in some form, but last time I checked, even the SSD wasn't working on Intel Macs under Linux.
It runs well if you have the time, patience and expertise. There's no fundamental technical barriers. It's purely a matter of enough development resources being committed to the project. I think Apples recent moves would motivate more developers to work on it.
