>I'm not convinced. If city-state is a city and a state in one, then why do we have two objects in Openstreetmap?
imho: compatibility with (old) osm softwares; (old) data models ( see more https://2018.stateofthemap.org/2018/T107-Modding_the_OSM_Data_Model/ ) for example: https://www.openstreetmap.org/node/1790048269(as admin_centre) https://www.openstreetmap.org/node/6684051501(as label) - has a lot of "name:*" tags. - then later wikipedia and wikidata tags has been added - now lot of rendering software can extend the name translations from the linked wikidata label. ( solving the licensing and tag inflation problems ) So some softwares using the wikidata for labeling. Imho: the real problem, why we have multiple objects for "name:*" tags?
