I would say that there is. Both Xamerian and React Native use the platforms Native views: UIView on iOS and View on Android. I agree that they are just bindings but that is easier then having to reimplement them as they all have small quirks especially when accessibility comes into play. I can't speak of Xamerian but I've written some of those Native bindings for React Native and would not call it requiring 'heroic courage'. It's actually quite easy and if you were on the Native side you'd have to make those changes anyway because those APIs changed.
