I don't yet know if there is a solution to this which doesn't involve some management software decision (e.g libvirt or higher).
If we use a new hint, there's no problems with migration from/to older QEMU and libvirt's host-model/host-passthrough would pick up the bit automatically.
(I'm not sure if libvirt knows that hints can change across migration, though).
