Had, past tense, because of the metadata situation and the lack of pre-built wheels. The ecosystem has moved on.

Show me a Python tool that you can install and have work out-of-box with uv, but cannot install and have work out-of-box with pip.

I have repeatedly shown that the slowness of pip is overwhelmingly due to its terrible (organically developed on top of legacy cruft from an era where people simply didn't have the same requirements) architecture, not due to being written in Python. Most of the work of installation is simply not CPU-bound — why would it be? — and the main task that is (optional pre-compilation of Python source to .pyc) is one of the few things where uv is dependent on the Python runtime (which, in turn, will do the work in C).
