From my understanding, this:

>Right now when you use your trackpad, or when you use the wheel and there are no `wheel` event listeners [...]

Needs to be changed so that it checks if there are `beforescroll` event listeners too, aside from `wheel` listeners. If nothing is listening for `beforescroll`, nothing can prevent scrolling and therefore, the browser can use accelerated scrolling?

You could also flag the `beforescroll` listener as `passive`, just as you can do with `scroll` and still benefit from accelerated scrolling?
