The biggest issue I have is not even for stylistic purposes. The issue is, json results for artist page will NOT show country when a city is used as the area. Unless the city has an ISO-3166-2 code (which very few do, as they are for state/subdivision). For example, Mobb Deep only shows Queensbridge, not United States or US-NY: https://musicbrainz.org/ws/2/artist/d75d1f08-bbb8-4eae-9877-399ca9121197?inc=aliases&fmt=json
Louis Armstrong area is set to a state, so US-LA is shown:

This is my reasoning for sweeping changes to area. Admittedly, Berlin has an ISO code, so I’m not sure why it wasn’t showing on MB json.
Applications that use MB data, such as Plex, use the json form for all their data. So when the json doesn’t display a country, Plex will not be aware of the country.
