I don't think we fire touch events on OSX, so probably not an issue. I'm
confident Android's behavior is more compliant that Win8 desktop. Metro is
somewhere in between. Wes makes a good point in the next follow up about
moving simulated click events into shared code to help standardize. For now
behavior would be dependent on the widget backend. My goal here is to start
by getting the two win widget layers acting the same.
As far as moz simple gestures go, they are moz/chrome specific, so they do
not play into compliance. The metro front end doesn't consume these and we
don't have add-ons yet, and the desktop front end uses them sparingly (for
fake pinch zoom). I don't think there are major issues with removing support
for these on Windows. There might be some addons that consume them. Authors
could migrate uses to W3C touch events pretty easily I would think.

One of the concerns here is that since we do not differentiate the metro
and desktop browsers via UA, the two should emulate each other closely.
The browser would appear completely broken to content if the same UA
sent two different event streams. So we need to take into account how
metrofx works as well.
How does the current/proposed state of affairs compare to other
platforms (notably OS X and Android)?
While the Metro-vs-Win8 case seems especially important to get right
(since the same user on the same device may commonly flip between both),
I'd hope web authors can write/test for on one platform and be
reasonable able to expect their code to work the same everywhere. It's
not clear to me how that ties in with what you're talking about.
