Yes. The same conversation is happening right now in the living room, because security has forced three reboots in the last year, after having several years where simply by being xen and pv and using pvgrub (rather than loading a user kernel from the dom0) we haven't been vulnerable to the known privilege escalations. This is a lot more labor (and customer pain) when you can't move people. No progress on that front yet, though.
