Oneiric is old hat. I'm cool with 0.9.5. If someone wants to spend
time building an inferior (i.e. that requires more downtime during
snapshotting) implementation that works with older versions of
libvirt, that's fine, but as a project, my view is: There's excellent
free software available that enables us to build cooler things faster.
We should use it.

Besides, libvirt 0.9.5 has been out for over 6 months. It's not *that* new.
