They very likely could not actually get any developer they want on Pokemon. Atlus, Square, Bandai-Namco, whoever..."It's Pokemon!!!" doesn't matter, most of these companies have their own things going on and wouldn't drop everything to do bi-yearly Pokemon releases. Grezzo & Arte may not have the bandwidth for their other projects.
And of course there's the possibility of costs involved.
ILCA could be cheap, they have their hands in a lot of different games, they seem to have their hands on the ability to pull in a lot of contract workers which let's them dig into more projects and they likely built up some behind the scenes agreements from their work on Home and now BDSP. That last part might be extra important since the ILCA people could have actively approached GameFreak.
Despite the narrative people desperately wanted to push, it seems to me that GameFreak did like the possibilities ILCA brought to the table. If they're making a distinct Divison they probably want to continue to foster that and probably allow more oversight/time/whatever.
