I wouldn't worry too much about these very generic classes of human
settlements or administrative areas. It would be better to focus our
attention on the actual Wikidata items on settlements and administrative
areas of each country, like Waldhufendorfs in Germany (
https://www.wikidata.org/wiki/Q351190) or comunes in Italy (
https://www.wikidata.org/wiki/Q747074). These national subclasses should
then be classified as subclasses of whichever appropriate generic
settlements or administrative areas there are.

So I doubt that tens of thousands of towns in Wikidata suddenly lost their
political territorial entity status. I would think that some of them are
still classified as such because of a different path up the ontology tree.
