I keep hearing the "You have go to all in" argument from React Native evangelists, but I haven't heard a reasonable explanation for why this would be. Why was Facebook able to introduce it within an existing native app? This also seems to contradict one of the major selling points, that you can always just drop down to native for problems outside its scope. This is a very important requirement for any company building more than a simple CRUD app. A simpler explanation is that "you have to go 100% in on React Native" self-selects for anecdotes from tiny companies tackling trivial problems, and allows one to say "No true scotsman" when a bigger company has a bad experience.
