That's only going to affect part of your apps though. Last I checked, Firefox on Ubuntu finally had a kind of pixel-perfect scrolling, but it wasn't smooth and didn't keep momentum if you let go of the trackpad while scrolling fast. That just feels bad, even after getting used to it.
And Qt apps will scroll differently than the GNOME project's apps which will scroll differently than other Gtk apps. It really feels disorganized and unfinished.
