Finding projects "low on maintainers"

Lex Fridman recently published an interview with Guido van Rossum where Guido says, while talking about extensions in PyPI that would need to be recompiled for 4.0, “some of those extensions are currently already low on maintainers and they’re struggling to keep afloat.”

I’m always on the lookout for projects that need help, so I’m interested in figuring out which extensions these are. The remark is roughly here:

I’m also more broadly interested in finding open source projects where help is needed and could be reasonably described as supporting global health in some way. No doubt this includes Python and many of its packages used throughout science and engineering, but I don’t know of a good way to find ones not already receiving ample attention.

Any suggestions or ideas?

Look for projects on this list, which don’t have Trove classifiers for a supported version (although a few intentionally don’t use version classifiers):

Look for projects on this list which don’t supply wheels (only 5/365 at the time of writing):

You could write a script to check packages on this list to see when the last release was made:

This data dump also has upload times for all packages:
