This isn't so much a bug report as a precautionary check, to make sure that a change to the structure of maintenance categories at EN isn't going to affect the operation of a Toolforge tool -- specifically, the Untagged Uncategorized Articles tool at https://tools.wmflabs.org/dplbot/cat/untagged_uncats.php .
Following a consensus that there is no longer any significant value in sorting uncategorized stubs separately from uncategorized non-stubs, the "Uncategorized" and "Uncategorized stub" templates have now been merged, the separate "Uncategorized stubs" queue has been deleted outright, and stubs now just sort into the same maintenance category as non-stubs. Accordingly, I just wanted to ask if somebody with maintainer access can do a quick check of whether the tool is depending on the deleted "uncategorized stubs" categories or not; if it isn't, then no further action is needed, but if it is, then the stubs categories will need to be removed.
