This is correct.
I've said before that Naboo and Coruscant are the only two locations from any of the 9 films that would both allow for a visually interesting theme park land and make sense as a land (i.e., be able to have shops, dining, etc. -- couldn't do that on Endor, e.g.) . Naboo is doable -- although it's really just kind of a mishmash of Byzantine/Baroque/Rococo styles -- but that's a prequel setting. I don't think there's a way to pull off Coruscant.
People clamor for Tatooine, but Tatooine would be as bland as (if not more bland than) Batuu.
And this isn't a defense of Galaxy's Edge, because I think they missed the mark there in multiple ways (at least some of which are fixable if they choose to do so). I just don't think there was anything wrong with the idea of a new setting.
The other idea, and probably the better one, would have been to avoid any kind of immersive setting at all. Just build a Star Wars area with dining, shops, and attractions that don't have to fit into one specific location.
