[Tagging] "part:wikidata=*" tag proposal for multiple elements connected to the same wikidata id

[Imre Samu]

>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? ( admin_centre, label, relation, ... )
