I am excited to see this. I would love to be able to run NetBSD on the new Apple Silicon. Currently have my 2015 MBP dual-booted with NetBSD (i only maintain big sur on it due to school). If this gets some serious support, when it comes time to upgrade (after I am done with school), I would definitely consider getting an M1 to run NetBSD without dual-booting. As defiling Apple hardware with FOSS is kind of a guilty pleasure of mine.
