One of uv's justifications is that it isn't dependent on Python, and so there's no circular bootstrap problem. Things are now at the point with uv were you tell the person you're sharing a script with: 1. Get the install command from the uv site and run it (if they don't already have it installed). 2. Run the script with uv.

Literally cannot get simpler than that. Making uv an importable means assuming Python is present or easily installed on every system, which if it were the case then uv wouldn't be becoming a thing.
