Need to free up space on PyPI

The latest build succeeded, but PyPI only accepted some of the files because we're hitting our 20GB quota:

We do have a lot of old versions. Each recent version is over a gig. The recent alphas that we used for testing are a great candidate for delete, and going back we could keep only the latest point release to free up space.

Note that despite what the badge says, only some 9.3.1 files are up. Once some space is freed up simply rerun just the upload step in the link above (shouldn't have to rebuild all the wheels).

Can someone with PyPI access free up some space and press that re-run button?

Done, and uploaded.

I deleted the alpha releases as you suggested.

What should the long term strategy for support be to stay within the space quota?

We should keep all source distributions, forever, except for pre-releases
We should keep all wheels for a limited set of recent releases
- Should this be based on version number? For example, support the latest X version (e.g., the latest 7, 8, and 9, so we would have 8.2.1 and 7.4.4, but not 8.0.2.) or X.Y version?
We should delete old wheels when needed (it's cheap to reupload to PyPI)
When we delete wheels, should we keep manylinux wheels for longer?

Also, perhaps we could look into using Py_LIMITED_API to reduce the number of wheels.
