It is already happening and with the help of some known personalities in the Rust community [0].

Rust has had at times multiple members of its leadership team employed by Palantir and not imploded, so probably not.

Sheesh. And you can't write a reproducible compiler for Rust either, because every version of rustc was compiled with the previous version. What are the chances there isn't a backdoor?

mrustc, an independent implementation, has produced identical output.

> rustc bootstrap tested and validated (1.19.0 isn't fully repeatable, but later versions are)

This means you'd have to land the same attack in both mrustc and rustc, making the possibility infinitesimally small.
