I do somewhat doubt that. `no_std` Rust is still quite different from normal, userspace Rust. You don't get all the fancy libraries or whatever (of course Linus would probably just veto them anyway) and the Linux kernel development model is probably quite different (IIRC no cargo and whatnot).

So… what should we reckon? Would there a difference in getting new developers into `no_std` Rust in the kernel, and how different would that be versus having people learn freestanding C, with all the kernel add-ons and nicknacks?
