I understand the sentiment. But the people who could work on the Asahi Linux graphics stack are generally not the same as the people who could e.g. bring up Asahi Linux on M3 chips.
I would not consider the lack of activity in some Asahi Linux areas to be a conflict of priorities. It is in my opinion mostly a result of these lacking areas naturally attracting less developers capable of moving them forward.
The M3 GPU is a lot different and has a bunch of new features like ray tracing, so the super talented team working on the Asahi Linux graphics stack might have a lot of work ahead of them to support the M3's GPU fully as well.
God I wish I was smart enough to help out with Asahi Linux...
