possibly if i recall developers will go through several ideas and possible rooms before they make the decisions on what the players actually see and any rooms left over might just be used for something else until the devs remove them entirely or use them as a place holder for a new dungeon after all it would save time to use something thats already there but not being used.

then again maybe i'm wrong since i don't really know anything really about game development but this would make the most sense to me.
