But how would it be a simple decision if Pets wasn't even going to be on a large plot of land to begin with?
As I mentioned in my edit, what you describe, sounds like not only a dead end, but entrapping one side of the park. It'd be a slap in Universal's face, especially considering the growth they've been doing, to when they can gut the TWDA Showbuilding portion, tear down the Globe, and have a .83 acre attraction, that would've been on similar footing to SS28's, perhaps more (I'm going off of estimations from when I looked at the pitch concepts, which we're leaked for that attraction by Alicia).
I don't think we'd lose the vision if TWDA is incorporated. And honestly, I'd rather want them to have it there, than to entrap a portion of your park with a dead end.
EDIT: And just to show what I mean, a rough guess of what you are thinking of.
