The Diamond/Pearl remakes might fill the gap.

Yeah, IMO, To me, it sucks a little bit not all Pokémon are gonna be in it, maybe Pokémon HOME can have a function to allow Pokémon not available in Sword and Shield to be returned back.

I even wrote about Galar in the AU banning outside Pokémon to preserve their own.
