With what's currently in the spec, you'd have to replace the  
addEventListener property in many places.

Yeah, it's definitely suboptimal at the moment.

You couldn't have both Node and  EventTarget be the prototype root in  
the current model. But maybe there could be way of specifying that  
the  EventTarget prototype goes above Node's, somehow.
