I never understood this either.
It seems like since 2017 Capcom hasn't really cared about games that weren't developed in-house. The only game I've seen since then that wasn't developed in-house was Monster Hunter Stories 2, but it was still 50/50 developed with Marvelous.
It's all about in-house development and RE Engine for Capcom now. It's paid off big time up to this point.
