They haven't publicized it because it doesn't actually do anything until you have an app that makes use of the API. If it's not turned on, the app will prompt you to turn it on when you install it. I live in germany, where the app is already released -- the settings panel shows a list of installed apps that use the API, but the app is responsible for the synchronization of the randomIDs with the server, notifications, etc.
