I guess I'm missing something then. The Asahi blog says "Apple’s boot tooling will only work with what it considers to be a “valid” macOS installation inside an APFS container." Sounds very adversarial to "the ability to boot an arbitrary OS."
replyIt basically just has to look like macOS in some trivial sense, it doesn't have to be macOS, there are no obstacles. The system is designed specifically to enable booting custom compiled kernels and former members of the Apple team have said booting other OSes was intentionally left open. The company just doesn't make any guarantees about that.
