In this case it seems like they transitioned a mostly native mobile workforce into React Native, so I don't know that the last bit makes much sense here. I agree with you that there is a general absence of information about how they still deal with the native side of everything with React Native becoming more and more important in their apps. Even just the "yet-to-be-transitioned-but-we-need-to-use-it" kind of stuff would've been more interesting to learn about and certainly "What native stuff remained in sections that were ported?" seems reasonable as well.
