Probably a roundabout way to get people to play the questline. They did spend quite a lot of time and money on it even if it splits opinions hard.

I have no idea where they are going with it, Dalmasca had potential to be Bozja like zone but got resolved in the Bozja notes. Maybe they won't even use new side area for it.

I guess it could potentially have something to do with Gilgamesh looking for better weapons or Godbert crafting?
