I tend to disagree.
As the dom0 kernel drives the hardware and hardware drivers seems
to be the more prominent reason for moving to new kernel versions,
I would assume the dom0 kernel to be updated more likely than the
domU kernels.
And actually, filesystem forward compatibility is not that bad.

I'm not saying this can't be an issue, but I suspect it won't be
for most people.
