It seems to me that it will be the case that for a given element
you'll sometimes want to do smooth scrolling operations and sometimes
instant operations.
For example in a list of emails you might want to enable
smooth-scrolling down 50 emails, but if additional emails come in, you
want to be able to add to the top of the list and atomically "add to
scroll scroll position" to compensate for the added elements.
FWIW, XUL scrollboxes support both smooth scrolling (JS implementation
using requestAnimationFrame) and instant scrolling. The tabstrip on
Firefox desktop uses both methods. Which one is used varies from case to
case and is controlled by the callsites. I agree that a CSS property
doesn't satisfy this use case well.
