I really wish Apple would fund a small team to open source some documentation and drivers to help Asahi along. I know they won't, but I can dream. It would be a drop in the bucket for Apple but would cement their hardware as de facto for silicon valley engineers (even more so than today).
Apple's own hypervisor framework is close enough to what you said that i run Fedora and Arch Linux builds via the UTM app, set to use Apple Silicon virtualization (_not_ emulation), which is a wrapper around said framework.
it's excellent, and made me reformat and erase Asahi a couple years ago.
https://developer.apple.com/documentation/hypervisor
https://docs.getutm.app/installation/macos/
So osx is just a bootloader for Fedora?
the analogy (even if humorous) isn't exact, since i can have apple silicon's hypervisor running macos and fedora/arm and arch/arm all concurrently, and can have full desktop environments on the linux instances, full-screened to individual macos desktops.
