All major distributions ship their own compiled rustc/cargo packages already, and they’ve done so for years. And putting rust projects using nightly features aside*, stable rust version updates are much less disruptive than major GCC or clang updates. Breakages are rare, known in advance, and communicated to upstreams before hand (look up “crater” if you want to learn more). * Not sure if distros package, or need to package any such packages, but I didn’t do any surveys on the subject.
