classifiers = ["Private :: Do Not Upload"] short-circuits uv publish entirely

[heyitsaamir]

Summary

The guidance on not publishing private packages is to add classifiers = ["Private :: Do Not Upload"] in your pyproject.toml file. However, if you do that in a workspace, and use uv publish, we see:

Caused by: Upload failed with status code 400 Bad Request. Server says: 400 'Private :: Do Not Upload' is not a valid classifier. See https://packaging.python.org/specifications/core-metadata for more information.

and the packages that do need publishing are also not published.
