Exactly, they wouldn't. The way Disney do lands is there has to be at least 1 attraction, 1 restaurant and 1 shop. If they divided Dinoland into two mini-lands, they'd need to add a restaurant to where Dino-Rama is (where Encanto will go) or put Restaurantasaurus on the Encanto side and add one by Dinosaur. Also, Encanto is replacing all of Dino-Rama and the carousel is replacing the Boneyard, so there isn't physically enough space to have Encanto, Carousel, Boneyard, Dinosaur, 2 stores and 2 restaurants (not food stands) plus any potential animal exhibits
