In the recent days I noticed an increase in conflicts about category renaming. Two cases: Category:Churches_in_Italy (and others) and Category:Cities_and_villages_by_country
I think we would benefit from a formalized system for category renamings. The damage is enormous if a well working category tree gets destroyed or damaged. Currently all places worldwide are categorized as cities independent of their size!
An idea could be that there must be a deletion request for the category to be moved. What do you think of this?
