I concur.  Thanks for the details of why IE has this.

If something like IE's content zooming is standardized then I think we
might end up wanting zoom here too.  Jacob, you were going to do some
thinking around extensibility of touch-action, right?  How do we design it
now such that we can add things in the future without breaking sites and
(ideally) without it being obviously discontinuous?

I'm OK with this, but I agree with Matt's concerns about leaving things
unspecified.

Jacob has mostly convinced me that solving this problem really must be an
'opt-in' mechanism (there probably is no good general solution that doesn't
involve opt-in).  In that case, are we OK with the idea that some
implementations (and ideally some future version of PE) augment the rules
here to define a different behavior when a site explicitly asks for it?  In
particular, IE10 has this:
http://msdn.microsoft.com/en-us/library/ie/jj152135(v=vs.85).aspx.  If
we're OK with such implementation-specific extensions to the standard and
with the idea of adding such an extension in the future, then I'd probably
prefer we keep the current strict wording.

Will reply to the thread.
