a lot of exposure to that code. I do know there's still upstream qemu work taking place. We really should be very careful about adding anything to libvirt before the upstream work is done. In particular any x-* command support.
AFAIK full pull backups as well as full/incremennal push backups are ready to use in qemu. It is a pity that other commands that helps organize pull backup process still has experimental status. One day they drop this x- and I doubt that things will changed very radically in comparison to what we have today. So if with the help of community this patch will be ironed out libvirt will get pull backups instantly after qemu be full ready.
FWIW: Happened to be scanning through qemu-devel today and came across the following topic (which interested me because it's related to other work I'm involved in):

Anyway a few responses in there's this:

Since you do rely on blockdev-add - I'd just caution you to not rely on something specific...
