Yet if I want to contribute to Rust backend, or its upcoming GCC implementation, write C++ I must.

Same applies to the runtimes of the languages I use at work, and GPGPU related tooling when not using shaders.

Maybe then do a Go/zig/D, focus on cranelift and fully bootstrap Rust, before trying to rewrite the world.

You certainly can go work on Cranelift or similar projects which have a coherent IR as a central goal rather than eh, it's probably good enough to compile C++.
