The problem is Apple's vertically integration of their software and hardware without much of the public documents make it very hard to develop open source for. And the fisaco between the wider Linux kernel community and Rust camp, of course. marcan quit because of the Rust drama last year (just one year ceremony recently ironically) in Linux kernel.
PS: btw I'm of the anti-Rust in Linux kernel camp. I'm a Rust enthusiast, but I just don't believe Linux kernel is the right place.
It's 2026 and there is still no Cargo support to build kernel modules. You still need to make linker script hacks to add the object file into the makefiles, and you tell me that is "out of experimental status". I asked for Cargo support in 2020 IIRC and it is still not here...oh boy.
That means dependencies still have to be vendored by hand-picking and we cannot rely on scanning the dependency graph for GPL.

Redox would fare much better.
