Problem you have encountered:
uv (https://github.com/astral-sh/uv) is a new Python package manager designed to be a replacement for pip. It downloads packages in parallel instead of synchronously and it is also written in Rust instead of Python (so way faster). As a result, uv is triggering a rate limit for Artifact Registry making it impossible to use it instead of pip.

uv also does not depend on caching headers like pip does, so this would be a full replacement for https://issuetracker.google.com/issues/275859622 if we can get uv working.
