I just went through that thread. There are some open questions. Also Jan
requested that you explore other possible options.

My current plan is to not block the release for this -- we're very close
to the anticipated release date, and posted-interrupt is either
technical preview or experimental, so bugs there are expected.

This issue will be listed as a known issue for PI. And you can continue
to develop a fix for it. Your fix will be integrated with next version
of Xen. Then you can request for backport to 4.7 if you want to.

What do you think about this plan?

Wei.
