I'm sympathetic to these concerns, but, unfortunately, I don't see any
other path that leads to interoperability with Internet Explorer.

As far as I can tell, the underlying problem is that Apple as not made
the usual IPR commitments regarding touch events.  For example, Apple
has not joined the Web Events Working Group in the W3C [1].  As a
result, Microsoft has chosen to implement pointer events in Internet
Explorer rather than touch events.  Moreover, Microsoft has been
willing to support the openness of the web platform by joining the
Pointer Events Working Group in the W3C [2].

Do you see another path that leads to interoperability?

If you would like to provide technical feedback about the
specification, please join the W3C Pointer Events Working Group and
provide the feedback in that forum.
