Like others have said, they didn't really make that much from Legacy, but I wouldn't call it dead. It's one of those properties that Disney will randomly do something with, whether it was something like Tron 2.0 or the Shanghai ride.
If Uprising came out when Disney+ was around, it would've had a better chance for more seasons.
