I thoroughly enjoy uv, having used poetry and requirements.txt prior, but it does come with its faults in a large codebase. Admittedly, I don’t know whether they re due to uv’s infancy, or PEP restrictions.

For example:

    1. uv sync should update by default (like poetry)
    2. uv lock revision and dependency resolver keep changing and it makes it hard to figure out if changes to our uv.lock are real or due to separate versions of uv among developers
    3. uv pre-release dependency rules should be able to be disabled with either a sys_marker or specific case like pinning a version
 

Some other pain points but I can’t remember them all at the top of my head..
