I think this is measuring '"stars" along a stability scale'. It's possible (but not proven) that stars *might* measure popularity to some degree, but PRs and issues is def a measure of stability -- more issues and PRs means it is changing a lot or has a lot of bugs or new features. This is not measuring popularity at all.
