Yeah, I mean, it's not my favorite and I obviously would have preferred meet and greets go in a still-existing other half of CommuniCore, but at least what they're doing is fairly malleable since changing it up likely only requires different digital assets.
If I had my way, I'd have further played up the "Disney World exists in MCU" aspect of Cosmic Rewind and made it into the Collector's EPCOT Archives or something. Make the dome into a museum with cases full of artifacts from old attractions, style the Cosmic Rewind show building as an automatic retrieval archive connected to the dome via some sort of lift, and then attach some VR theaters to the back. Pre-show is a faux "lift" that takes you into the archive with some narration from and footage of Benicio as the Collector, and the various shows you view at different scheduled times are virtual recreations of past attractions like Horizons, the Maelstrom, 20000 Leagues, etc. using archival audio and whatnot.
Buuut I'm armchair Imagineering to the max now. I'll stop.
