I don't know about React Native, but Telerik's open source project NativeScript promises to always have 0 day support of all native platform features since it's reflecting over the native platform's libraries to expose to its own API.

React Native and NativeScript seem to have all the upside of Cordova (transference of web dev skills to native platforms) with none of the downsides (lag in new OS feature implementation, webview wrapped apps), I wonder if Cordova's days of relevance are numbered.
