What happens if Apple decides to start rejecting these JS->Native Code apps built on frameworks like React Native? Because in theory it is possible to update React Native apps remotely bypassing the App Store approval process.

2.7 Apps that download code in any way or form will be rejected

2.8 Apps that install or launch other executable code will be rejected

One clarification here. Drifty/Ionic is not native...it's "hybrid", which means it simply wrapping AngularJS into a native container.

React Native actually compiles Obj-C (much like Xamarin) which is what makes it fairly revolutionary. In other words, it would be very difficult to tell the difference between someone writing native Obj-C with someone compiling it from React Native. Drifty/Ionic is simply doing transitions, taps, using the JS engine of the phone.
