It's easy to get trivial examples of native integration working, but as soon as you try more complex things it starts to break down. Code push? Oops, your native integration in old app versions just broke. Share an existing native UI library? Sorry, Yoga has its own (incompatible) thing going on. Yes, there are workarounds for all these things, but at what point does the overhead defeat the purpose?

Also, the security and performance implications of the Javascript dependency ecosystem should not be ignored.

Small greenfield app on a shoestring budget? It's perfect for that.
