So, if the defaults work quite well for you, I conclude that your vote
is against changing them.

The recipe is: visit a (large enough) file and scroll through it by
spinning the wheel of the mouse quickly enough (e.g. 4 "wheel steps"
in half of a second approx.).  Maybe you can't reproduce this on your
environment, I don't know.  In all the environments I've done that,
the scrolling is too fast and accelerated.  I can't imagine who may
want that behavior, but maybe there are some people who do.  In any
case, it seems clear that most people don't what this feature, hence
it should be disabled by default.
