Makes sense, but how would that be labelled. Any documentation or written/printed representation would need a label (preferably a consistent one).

Taiwan, China or just Taiwan?

What happens if you need to display a map of a contested area? any represenation you show will raise the hackles of some nation state or other.

"Which country it is shouldn't matter much." is an admirable goal, but at the risk of being pessimistic, it just isn't how nation states work.

You simply report/label on a very local level (city/town level) because that's what will really matter for further action. If necessary, report coordinates.
