>>39168307The way I see it, it's like the 3DS Pokédex App. The game served as an excuse to kickstart labor to update every Pokémon model up to BW1. In this case it's giving every mainline trainer thus far a 3D model to save GameFreak the time and labor of building hundreds of characters from their transition to 3D.
Even if they won't be used in a mainline game on a console/handheld, it's giving the option for it without sacking the development time.
