This is actually already used nowadays. Whenever you implement a browser
object in another application (like the IE object in Visual Studio), you can
capture these bubbled events in your application. Good thing that it
actually stayed in the specs :)
We use that in our call scripter tool for contact center agents.

My understanding is that the only noticable effect of defining that
these effects bubble is that their bubbles property is set to true.
Same thing happens to bubbling events fired at an XMLHttpRequest
Of course, in a theoretical future where we'd add an object "above"
the Window object, these events would bubble to that object. But
that's not the case today as no such object exists.
