building=Utility doesn't seem to be a vaild tag. Should this be changed?

opening hours 10am–5pm every day including public holidays (would add it in myself but osmand cant edit way tags)

Is it not better to leave the name blank instead of add unknown?

The place has gone or never existed. This is an auto-generated note from MAPS.ME application: a user reports a POI that is visible on a map (which can be outdated), but cannot be found on the ground. User comments: "looks like this place was replaced with nord burger" (OSM data version: 2017-03-28T20:59:03Z) #mapsme

Should there be buildings on top of buildings here?

New house here which is not yet on bing or mapbox images
