And if it's meant to be a React alternative, then I suppose it should support native as well.

React-native doesn't care on the other hand if the payload is 20kb smaller. Never seen a drop in replacement for it.
While it may share a common history and core with ReactJS, React Native is really a separate beast. I realize it may be confusing due to the overlap in names. When people say React they are generally referring to https://reactjs.org and not the intersection it has with http://www.reactnative.com/ or the union of the two projects.
The official docs for React Native are at http://facebook.github.io/react-native/ by the way.
While React Native makes use of the react core package, it is a separate github project http://facebook.github.io/react-native/
