I'm sold. Never going back to pip/twine/requirements.txt again if I don't have to. I have several projects that all share a common wheel hosted on an internal GitLab instance, and I was able to replace like 10 lines of YAML with just "uv build" and "uv publish." Importing is quick and easy, and you can see what your core dependencies are as opposed to everything just being in one mess of a requirements.txt.
