Pretty much agree with everything you said. I'm an iOS/Android dev with about 7 years of mobile development experience and I have shipped two apps using React Native.

I think the biggest problem with adopting React Native in a shop that already has a native team is politics. Lots of Native developers don't want to touch it.

I think it's a great fit for companies who already have a React front end team and who's mobile teams are at least open to giving it a try.
