Sp this effectively means gcc is a second class citizen and even if
gcc is supported
at some point one needs a super recent gcc *and* rust toolchain to build
a rust-enabeled kernel?
I understand that this is right now not a big deal, but as soon a
non-trival subsystem
is rust-only people are forced to upgrade.

Don't get me wrong, I'm all for having rust support in Linux.
But I'm a bit worried about new dependencies on compiler toolchains.
As someone who works a lot with long supported embedded systems I learned that
as soon an application gains a hard dependency on clang or rust I'm in trouble.
