They should definitely take more of the Universal approach and stay quiet, at least on details, until closer to reality.
The microscope of fandom is the problem. And expectations are everything.
While Galaxy’s Edge was being developed, I was not paying any attention to WDW. I knew they were building a Star Wars land, that’s it. After it opened, I heard that it was tough to get on Rise.
I didn’t know or expect any of the extra features the OP mentioned. So, when I eventually visited, I was blown away by what is there. I loved it.
Compare that experience with someone grumbling their way past Millennium Falcon, seeing only what was missing.
