I searched and didn't quite find anything like this. The problem is that when you have an abusive edit that is removed entirely from the database by an oversight/office action, it can leave behind an abusive edit summary and a standard admin with revdel capabilities cannot remove this. See the attachment.
- T20598: Create a maintenance script to convert oversighted content to suppressed with revision deletion, and the corresponding log entries too
- T20455: RevDeleted links not available at times when they should be or may be urgently needed
- T20493: RFC: Unify the various deletion systems
