"Xen is not a full hypervisor until it loads the first domain - dom0"

Yes but the domU's can't talk directly to the dom0 without going through the hypervisor code though can they? This means that dom0 doesn't have to be provably secure if the hypervisor is. The hypervisor is acting like a firewall between networks, and the smaller and simpler this bit of code is, the easier it is to reach higher levels of certainty that the system is secure.
