Reasonable people can disagree with you on the point that Rust is more safe because you can write unsafe code in Rust, whereas in Fil-C you write unsafe code in the compiler. Why might I write unsafe Rust? To do something not particularly fancy. A use case covered by normal safe Fil-C. Why might I write unsafe Fil-C (compiler) code? To improve compiler or runtime performance or add new platforms, etc. Analogous to wanting to work on Rust's IR or borrow checker. Very different use-cases.
