FWIW my current workflow includes building the kernel under macOS, so
there’s some interest from me, but that will pass once the porting
project progresses enough. So far I get by with some local duct tape.

I really wanted to do it in a VM as a saner path, but I didn't find
a satisfactory way to share the working source tree between the macOS
host and Linux guest (which wouldn't slow down the build).

Just for context: Most of our (Asahi) developers' workflow involves
loading kernels over USB from another machine. That other machine can be
any OS, but if it's another M1/2 running macOS you get the additional
perk of USB-PD tooling to remote-force-reboot the target machine as well
as get a real physical serial port. The same tooling could be ported to
Linux-on-M1/2 relatively easily, but nobody has done that yet (probably
because these days we have a hypervisor that gives you a superset of
that functionality anyway, over standard USB, so it's not that necessary).
I personally use an x86 host and a hardware contraption to provide the
same hard reboot/UART functionality (for the rare case when the
hypervisor borks, to avoid having to hold down power buttons).
So there are certainly some people who'd benefit from using a macOS
machine as a build host, either for the special USB-PD functionality or
because they just like macOS as a development environment. It sounds
like getting it to work isn't that hard, so perhaps it's worth upstreaming?

My way of doing this efficiently is to create throwaway commits, in
git, just to push code around to various physical or virtual machines
in my house. Because git is really fast at pushing incremental changes
around:
https://github.com/ericcurtin/staging/blob/master/git-push.sh
But if you eventually find a way to share a filesystem (which wouldn't
slow down the build) between MacOS and a Linux host via qemu or
something like that I'd be interested, that's most ideal of course.
