So, this died here. As things stand: I proposed removing the Xen
criterion, Lars opposed, we discussed the testing situation a bit, and
I said overall I'm still inclined to remove the criterion because
there's no clear justification for it for Fedora any more. Xen working
(or rather, Fedora working on Xen) is just not a key requirement for
Fedora at present, AFAICS.

It's worth noting that at least part of the justification for the
criterion in the first place was that Amazon was using Xen for EC2, but
that is no longer the case, most if not all EC2 instance types no
longer use Xen. Another consideration is that there was a time when KVM
was still pretty new stuff and VirtualBox was not as popular as it is
now, and Xen was still widely used for general hobbyist virtualization
purposes; I don't believe that's really the case any more.

So...with thanks to Lars / Xen Project for their input, I'm afraid I'm
still in favor of this proposal, and still think we should drop the Xen
criterion for F31. This wouldn't mean Xen is out of Fedora and we don't
care about it any more, or anything like that; it would still be a part
of Fedora and we still would like Xen to work on Fedora and Fedora to
work on Xen, just like any other non-release-blocking package. It just
means we would no longer block releases if it does not work.

Agreed.
