I still think that's a horrible missed opportunity. Would've been an absolutely fantastic little walk through attraction similar to Minnie and Mickey's houses in ToonTown mixed with Honey I Shrunk The Kids playground in Florida. Have some interactive props (that could work with the interactive wands), animatronic garden with animated veggies and magical creatures, and of course oversized furniture which would've made for great photo opps! If they wanted to, they could've also made it a dessert snack hut, since Hagrid enjoyed dabbling in very sloppy cooking sometimes, like cookies and cake. Huge missed opportunity, but at least it's something they can at least add in the future if someone ever approves it.
It would've been especially great in Hollywood, where they could've counted it as another attraction.
