The real problem here is the fact that active listeners are still a problem to begin with. It'd be absolutely insane if a native app did not get first crack at all input events. This is how they all work (iOS, Android, Windows - take your pick), and the mere existence of a touch/scroll listener is never a problem. But on the web simply having a scroll listener is such a massive performance issue that it's worth introducing not just a new API to get events after they've happened, but to then make that the default? Why not just fix the performance problem instead of hacking and slashing around it?
