Omarchy is built on Arch and there is a flavor of Asahi for Arch as well, so there's no reason it couldn't support the same hardware that Asahi does, just that someone needs to do the work.
Even then, Asahi is understaffed and a volunteer project following a hard and software product blackbox that's changing annually with little public documentation. I think M2s just got external monitor support via USB just recently.
It's been going slow because they have been focusing on cleaning up their patches and getting them upstream into the mainline kernel. Once that is done work on other hardware will speed up.
Didn't know that. Awesome, thanks for sharing this.
Going slow is an understatement - is it even being properly developed after the main personalities quit?
