In Mac OS, horizontal scroll is still respected and it only activates if you cannot scroll further.
If we want to keep a hierarchy (1 finger pointer, 2 finger app, 3 finger shell) it wouldn't make sense to jump to three fingers. And I think we want to use as few fingers as possible. 4 finger swipe to change desktops would be a pain.
