I entirely understand that.

If so, how? The changes to NSScrollView for responsive scrolling are all implemented internal to it and NSClipView, and your app is expected to rely on various new notifications to get hooks into various phases of the whole sequence of scrolling a view. There is no support or changes to NSEvent, and nothing in the -[NSResponder scrollWheel:] handler itself that has changed - only NSScrollView overrides that method to set up a private concurrent event queue. Maybe within that queue there is some private stuff that gives it more information but it hasn’t been exposed to the public.
