I will note that Ubuntu's rewrite of coreutils breaks a number of test suites (including xfstests) because its outputs are different and this breaks golden output comparisons. I expect it will also break various expect scripts that sysadmins might have in production.
Bug reports about fstests being broken on Ubuntu have been rejected[1] because it's perceived by kernel developers as Ubuntu just being silly(tm). Given that some rather the primary test regression appliance is based on Debian[2], I would consider it.... unfortunate and regrettable if coreutils were replaced by Canonical's rust rewrite. And that's before we consider the over 100 CVE's that were *introduced* by the rewrite of coreutils[3].
