Ignoring the anti-GPL nature of Rust rewrites, it seems that it has been foolish to roll out rust-coreutils wholesale instead of perhaps an option to be selected while installing from the live image, which would almost certainly have lead to enthusiasts testing these utilities; and after enough data had been collected could then have been put in the main branch.

This bug report is old so it should have been fixed by now, but I wanted to commentate on rust-coreutils.
