Actually I believe I said "at least one implementation".  I.e. those that
were never implemented anywhere (touchenter/leave) serve to only cause

That would be fine with me.  I don't think we should publish the v2 draft

webkit/blink implement radiusX, radiusY, force.  I think those are really
the only changes from v1 (along with initTouchEvent which we never specced
at all) that we have in blink/webkit.  I'd be happy if we just noted those
(and perhaps also identifiedTouch - but I don't have a strong opinion about
