You do realise that the way a game like this is constructed, it is quite likely that the overarching map was built up first on specifications and the actual locations were added while the characters, quests and stories were developed?
Why is that huge extra space, that *is not even part of the game* such a big deal? Did you also complain when Age of Empires 2 left easter eggs for cheaters by saying that they weren't making full use of the map?
