> underlying framework/runtime can generate the appropriate UI for the exact target platform

This may seem like a good idea, but it's not. What you will get is a leaky, lowest common denominator API that will break on each new OS version.

I don't understand how you got to this conclusion.

I worked on Xamarin app and saw how things worked there. I also think that it's a logical conclusion from these conditions:

1. You want to support N native platforms. 2. Each of these platforms has it's own way of doing this, bugs, etc. 3. Each of these platforms is being actively developed. 4. There are differences between those platforms. One doesn't have guassian blur, the other one doesn't have right-to-left languages.

RN is more flexible. And you can always contribute or build your own native extension to use.

Well put.
