Seems to impact Special:Renameuser which appears to only get 4 visits in the last year on English Wikipedia?
First, as @Krinkle wrote in T304276#7812901, page views are not reliable for special pages. Second, Special:RenameUser is not used on SUL wikis anymore, as SUL renames are done centrally at m:Special:GlobalRenameUser, so enwiki is not even relevant, only non-SUL wikis like chapters’ wikis, ArbCom wikis etc. And the fixes seem to be pretty straightforward, so I don’t see why they shouldn’t be done now.

The extension has no maintainer so it's not clear to me who will provide the patch and who will review it. Of course if we can patch it that would be ideal.
