yeah I am not sure either. It's also not clear which Jupyter subproject owns this repository and the `jupyter` name on PyPI.

Yes but I don't have commit rights on this repo (https://github.com/jupyter/jupyter). Which are usually necessary to push a new tag and probably also using the GitHub Action workflow mentioned above.

So what should the process be? Continue the conversation here with @jupyter/software-steering-council, or open a new issue somewhere else?

Closing as (likely) fixed. Please feel free to re-open if the issue still happens, thanks!

For reference the `setuptools` dependency was added in https://github.com/jupyterlab/jupyterlab/pull/16423. From https://github.com/jupyterlab/jupyterlab/issues/16404#issuecomment-2145957163: > If we end up adding pin we should make it >=40.1.0 as this is when find_namespace_packages was added....

I updated the top-level comment to mention the update of `setuptools` to it's more visible.
