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.
