Agents will arbitrarily change maps basted on what their current listing are and would happily change them daily. Longer term there is little point changing place names as changing demographics will eventually adjust the meaning of these names even if no lines move on a map.
Nobody/Everybody, if people start calling a region by a name it makes sense to record the usage and put it on the map. Sure, it probably makes perfections and planners twitch but it makes maps more useful.
I notice a lot of Americans love referring to Canada as “Canadia”. I can’t make a bit of sense out of it, but by your logic we should update the maps already.
