I believe 3.4.3 stable release would make sense only supporting pvops.
Otherwise, you already have 3.4.2. Maybe you care about xenified aka Suse kernels
It would be different concern.

I doubt anyone is running pv_ops dom0 in serious production uses yet. So I'm
not sure backporting this sort of stuff to our very stable branch is really
necessary. Anyone running pv_ops dom0 is likely not scared of Xen 4.0.
