I'm not sure if and when I'll have time to work on this. Closing it out for now. There is a rudimentary app at https://niharika29.github.io/wikitopics/ which is running but it could be way better.

[mediawiki/core@master] Add Special:CategoriesToEmpty

That's how the categories are returned before they reach JS.

By the way, many CSS rules should be updated from page-break-inside to break-inside.

The count in the database has three parts: "all members", "file members" and "sub-category members".
The page count is not tracked as own field, but calcuated by the others.

Recent changes is now maintained by moderator tools.

Some excessive linkpurge/nulledit also happen to fill the categories due to T373722
The next run of recountCategories.php should fix it.

If T50175 is doable, it's probably the best way to do this. That would enable other functionality and enable wikis to properly customize when they load editnotices.
