I wouldn't expect to see this region in the game nor would I expect to see the DogBed either. They're probably just testbeds for the dog. To see how well it behaves.
As for the Brightwood connection, that's usually too big of an assumption as they tend to use quite a lot of assets all around the game, it isn't really that region specific, especially when it's something like an outhouse, wall or something fairly generic.
But there are few interesting bits in there. I keep looking at that transportation folder. What kind of objects could you find in there?
