It's unfortunate in a lot of ways that this is all getting written before Rust support is in the kernel. If that was the case then all these new drivers could get written in Rust instead. Oh well.
As described, the crux of this work seems to be learning how to interface with Apple’s proprietary hardware. If Rust enthusiasts want to go back later and reimplement, they’ll have a working open source reference implementation.
Asking people to use an experimental feature that will probably be ready in a couple years only to write stuff today is an extremely bizzare thing to do.
