(i didn't read the whole discussion)

here's my opinion... some months ago i've suggested something similar on 
mozilla's bugzilla

i don't actually like the idea of the "smooth scrolling" argument of 
scrollTo and scrollBy methods, because i think this should be applied 
also to scrollTop and scrollLeft properties
i don't also like the idea of a global flag that enables or disables 
globally the smooth scrolling on cssom methods/properties

so what about something like this instead

html {  transition:scrolling 0.5s ease-in-out 0; }

this could be applied to any scrolling related event, for example when 
linking to a page.html#fragment , when set by scrollLeft|Top and co.

but, it's not easy determine how this should work... at a rough guess, 
here's some random ideas

         html { scrolling-x: 0;                 scrolling-y:400px; }
         html { scrolling-x: 100px;        scrolling-y: 
element(#fragment); }      /* this should not change the url's 
fragment... it just simulates a scroll */
         html { scrolling-x: 0;                scrolling-y: 
element(#content > p:nth-child(1) ); }

... and, for animating this:

html {  transition: scrolling-x 0.5s ease-in-out 0, scrolling-y 1s 
linear 0; }

maybe in a later moment, some more effort for this could be needed... 
for a better scrolling control

html {  transition: scrolling-delta-x 0.1s ease-in-out 0; }

hoping to be helpful...
