No. That’s round 3. Round 2 is already announced - they are ‘restricting’ environment integrity to multimedia on Android webview. Of course, what they don’t say is that the feature is going to be developed and tested outside the view of the general public - since this doesn’t need to go through a public standardization like web specifications. Once they get that perfected, they will silently expand its scope outside webview and gradually into browsers with a new name. That’s round 3.
