Hi, my goal was to remove the park from the map data with that tag and that name, and this worked. I'd heard it was permanently closed, to perhaps be turned into a different kind of aquarium with a new name, so the disused prefix  seems to accurately reflect its current real world state (existing but not in use) until more details come out. I've seen cases where the stated plan doesn't actually happen, or things to be demolished kept around and reused, so I just try to reflect reality rather than what's promised. You're more likely to track the future changes, when you feel like construction has started, feel free to update the prefixes.
