Between that and the uutils-coreutils, Ubuntu 25.10 sounds like it'll be an interesting experience for users, especially those with accessibility and internationalisation needs.
I fully agree with you on the accessibility front. It's not even good on X11, but it's unusable on Wayland, from what I understand :( Accessibility on Linux needs a massive funding and development initiative, and it needed to be done a long time ago.
But uutils is pretty solid. I've swapped out my GNU coreutils entirely (on Arch, not Ubuntu, because I value my time too much to be troubleshooting broken snaps) and haven't run into any issues. I think people are underestimating how close the compatibility already is. I'm sure something I use at some point will try to invoke an option that doesn't exist in the uutils version, but it's been solid for me so far.
It’s not the viability of the rust replacement of uutils that is the core of my issue. My issue is that mature code that has been tested, audited, and is stable has been removed for no viable reason other than it could have bugs.
It's not for no viable reason. Rust is just safer than C. There absolutely are bugs with GNU coreutils, so it's not even a hypothetical like you implied. But beyond safety, some of the Rust equivalents are more performant than their C counterparts.
And uutils is already heavily tested against the GNU coreutils. It's not some fly-by-night rewrite that people aren't serious about. I don't know if it's been formally audited yet, but it absolutely will be when companies like Canonical (and hopefully SUSE and Red Hat, one day) want to start shipping them.
