6th Gen Was there any beta ideas scrapped for a wild areas from galar all the way back on the 3ds?

Legends 2 trailer says there's going to be wild areas in lumiose city, but this isn't the focus of this thread. Were they ever planning to ever put wild areas in places like gen 6 Kalos/Hoenn besides the traditional routes? It stayed pretty much the same in alola, the switch version of Kanto and sinnoh. Scarlet and violets was more of an open world version of galar's wild areas, but way more natural in comparison. I think it just may be a coincidence and wanting to bring back a feature from Gen 8, but on a more scaled controlled environment. I know off topic, but remembering the wording of the trailer mentioned wild areas will be returning made me question if they were planned to replace routes as back as the 3DS era. If so, this was sign of evidence that the 3ds games were planned to be open world before the switch, but were scrapped for the traditional linear map.

Imo they were never planned for gen 6. Wild areas in Galar are imo the default way to showcase a freer environment in the newer games.
I justify those "wild areas" being back in Z-A only because the game takes place in one city, and somehow you gotta catch Pokémon, who can't pretty much live in a city if they at least don't get a dedicated environment.
So, I find the use of wild areas in Z-A to be a solution to a problem, rather than being an old scrapped/planned feature of 3ds games
