Asahi is all reverse engineering. It’s nothing short of a miracle what has already accomplished, despite, not because of, Apple.
That said some of the prominent developers have left the project. As long as Apple keeps hoarding their designs it’s going to be a struggle, even more so now.
If you care about FOSS operating systems or freedom over your own hardware there isn’t a reason to choose Apple.
Have they though? Hector just added support for the power button, I wonder if he is officially back?

To be clear, the work the asahi folks are doing is incredible. I’m ashamed to say sometimes their documentation is better than the internal stuff.
I’ve heard it’s mostly because there wasn’t an m3 Mac mini which is a much easier target for CI since it isn’t a portable. Also, there have been a ton of hardware changes internally between M2 and M3. M4 is a similar leap. More coprocessors, more security features, etc.
For example, PPL was replaced by SPTM and all the exclave magic.
