No, with accelerated scrolling I mean scrolling without going back to the main thread (async scrolling, etc).

Right now when you use your trackpad, or when you use the wheel and there are no `wheel` event listeners, and keyboard (at least Firefox allows in some circumstances to use accelerated scrolling when you use the keyboard, in some situations), etc, scrolling is pretty fast, because it doesn't need to go through the main thread and it's a compositor-only effect.

Your event would mean that the UA cannot really scroll without dispatching an event and then knowing if that event is default-prevented.
