The park has never had the room for big night shows outside of the castle. It's not that kind of park.
The park's footprint has already dramatically expanded and will continue to do so. You're complaining about replacements versus new additions when they're about to unveil an entirely new land that replaced nothing but a soundstage that wasn't accessible to park guests. Before you mention Special Effects Show and Animal Actors, those buildings were having major problems that all but required a timely replacement. There's no version where they stayed as-is. The truth is that the company, for the first time, has been consistently prioritizing the needs of the park over the needs of the studio.
The front-of-park redo was in no way a waste of time or space. It dramatically improved the entrance experience from what was there before. It also wasn't redone ten years ago - it was literally completed less than five years ago.
Respectfully, take a deep breath.
