Why can't this be a Setting?

Why isn't fast frame scrolling a Setting?

After discussion with Simon on irc, all what we want is a settings for "Fast Frame Scrolling" that can be an "experimental feature" (e.g. like SpringTimingFunctionEnabled) not a "runtime flag" (deprecated). I'll upload a new patch soon.

I wonder if we should call this "asyncScrolling" since we have AsyncScrollingCoordinator.
