Has the code quality in that repo gotten to a good point then? I haven't followed it much, but last I looked[1] (which was a few years ago) almost every tool I looked at in detail had pretty bad performance or correctness issues.

You weren't kidding: it was exactly 4 years ago ("September 13, 2022").
The reason for existence of uutils is ideological, not technical. Thus code quality is of no use for the objective.
