To be clear, I would not ordinarily ask these kinds of questions. I understand that things take time. That's why I'm resigned to the idea that Asahi will never again be roughly up to date with the latest Apple hardware. I only asked this question because hanikesn seems to think that Asahi will magically suddenly be up to date once they've upstreamed everything.
Would I be correct in thinking that once M3 is up and running, M4 (and M5?) - the basics at least - should be relatively easy due to architectural similarities? In the same way that M2 was relatively easy because it was quite similar to the M1?
