Sure, but it’s demonstrably better than Poetry, which was the best until uv.
If uv isn’t a standard, it’s because not enough people have tried it. It is obscenely good at its job.
False dichotomy. Been using pipenv for 8 years. At first it was a bit too slow, but at this moment it gets the job done.
standard
You keep using that word, I don't think it means what you think it means.
uv is young, unstable and still lacking in details. It has multiple updates per month, nearly every week there are significant enhancements and bug fixes. It's not mature enough for being a standard yet, even though, what it already offers is excellent. But let it grow, change needs time.
