Point being these are leaky abstractions. You have to have some measure of knowledge as to how the underlying platform works in a professional context.
The abstractions depend on the dev. The knowledge needed is considerably less to make an extension vs making a full native app.
RN is useful if you're a solo dev, like myself, or a small team and you want to support all platforms.
I have enough knowledge to get all my apps in production, enough to make extensions for the platforms, and quite a bit in web to remake native features on the web. I am not what I consider an Apple or Android dev though, far from it.
I can learn from a middle out approach when it comes to all platforms. Similar to compilers and such, you can always go lower level to understand more and more, but it's not needed to get your vision out.
