Does anyone know if M3 support is likely to lead to M4 or M5 support in relatively short order? AIUI M3 took a long time because it was a substantial departure from M1/M2, especially in the GPU architecture, but I don't know if M4 or M5 made similar leaps.
M4 is apparently even harder because of some new hardware-level page table protections.

The M5 reportedly has a newer generation GPU compared to the M3/M4. For one thing, the GPU-side Neural Accelerators are obviously new to the M5 series. Other stuff is harder to know for sure until it gets looked into from a technical POV.
The main reason M3 took a long time isn't related to m3 itself, but rather that the asahi project took on a ton of tech debt to get M1/M2 working. M3 wasn't too difficult, but before taking on the additional tech debt, the Asahi team focused on getting all of their changes upstreamed to the linux kernel.
