Lots of core UNIX and Linux projects are. C++ is not liked by a lot of low level FOSS community. I think Rust is going to get further into these areas. I know C++ well but prefer C. I know plenty of others who feel the same.

Yes, first Rust code was released in 6.6 I think and MS also started implementing Rust code in the Windows kernel.
