For the avoidance of doubt, this is a revert to the state immediately before the edits - it does not mean that previous values were "correct".  As an example, I'd expect that https://www.openstreetmap.org/way/1184324514/history would have names in both Ukrainian (name:uk) and Russian (name:ru), and that the "name" tag would follow the rules set out in https://wiki.osmfoundation.org/w/images/d/d8/DisputedTerritoriesInformation.pdf .
