It’s somewhat inevitable that something will try to replace the C implementation of coreutils. Hopefully uutils will fix whichever bugs are reported upstream to lower the compatibility load though

At least it's somewhat possible to reliably test behavior of these against GNU coreutils. Pull down some archaic C++ project with a pile of janky shell scripts involved in the build (Chromium might be a good target) and compare final results.

One could argue that building Gentoo is an excellent way to exercise things:) Which, granted, is kinda cheating since you could just `emerge chromium` or whatever... but IMHO even just making portage itself happy is a good first step.

Why? Are you unhappy with the IMO very good test coverage, or has it not been working well for you the past checks notes decades?

Author didn't state a preference either way, but why do you care? Nothing is wrong with a reimplementation, as using it will nail down any untested/undocumented behavior of the original code.
