--- Comment #1 from Peter Hutterer <peter.hutterer at who-t.net> ---
We looked into this before we started implementing gestures, but here were a
couple of issues. Hans looked into this and when this recently came up in a
private discussion with one fo the googlers he wrote:

"From the top of my head the main reasons where:

1) The chromeos touchpad code came with a number of deps (besides it self
   being an extra dependency)
2) The chromeos touchpad code has lots of tweakable settings and basically
   came with a completely tuned per touchpad profile, this is doable if
   you are in full control of the hardware and have only a limited range
   of hardware to support, but is not really an option if you want something
   which works on every laptop out there.
3) We did not do gestures yet at that time, and for mouse pointer moving /
   2fg scrolling, our own code was more or less just as good, which combined
   with 1 and especially 2 made going with our own code the best choice
   at that point in time

I think (but I'm not sure) that there also was an issue with the chromeos
code always (or was it never ?) doing tap to click double-tap-drag, etc."

Unless something significant has changed here, this is still a no-go.
Unfortunately we spend *a lot* of time working around hardware that is
suboptimal and not nearly as much time focusing on hardware that is actually
good.
