Speaking as an innocent* bystander:

I would usually presume that I can use any recent libvirt to test
current QEMU, even bleeding edge. In this case, not even the latest
released libvirt version will be fine, I would also need to build
libvirt from git (which is probably not something a non-libvirt
developer will usually do). If everything goes according to plan, I can
only test QEMU with a released libvirt version at the very tail end of
hardfreeze, where only release blockers are appropriate.

I think it would be really beneficial to general QEMU test coverage to
push deleting this option back a release or two. We should make testing
QEMU in conjunction with libvirt as uncomplicated as possible.
