I have React and React-Native applications that are using Remote Config. Google recently released a real-time aspect of this feature to allow changes to Remote Config to get pushed to devices in real time. The React Native SDK for Remote Config supports a callback event that I can listen for and receive updates in real time. It appears that the firebase-js-sdk library does not support this. Are there plans at some point to allow web projects using Remote Config to hook into the realtime eventing the same way that it is supported on mobile?
