It's still early in the development of mobile stacks. It might be a huge risk to use a completely new framework built on another framework right now but in a few years it might have evolved to the standard way of doing things. If they get the tooling and own code to a stable state where everything just works it might save a lot of developer time. Or it might be safer to just go with Cordova or similar and use any UI and JS framework you like (that is stable enough).
