So maybe I'm stupid, but why would they be having heart attacks?

It seems like a decent solutoin to me.  What's being proposed would
make the dom0/hypervisor interface an internal once, always subject to
change.  What's wrong with that?  Presumably the domU/hypervisor
interface would have to be remain stable, but why is the
dom0/hypervisor interface have to be sacred and unchanging?  I don't
understand the concern.
