Congratulations, you’ve illustrated the difference between syntax and semantics. But any competent compiler also handles semantics (just in a separate phase of compilation), because that’s necessary for any useful conversion to machine code, not to mention optimizations.

I broadly agree.

However, “Existing maintainers have every right to push back where they see fit” is tenuous when the Linux project as a whole has already (exhaustively) discussed and debated this exact question alongside all the other questions about adding Rust, and the explicit declared direction is that Rust should become an increasingly large part of the Linux kernel.
