I don't think we can do this unconditionally. Apps which use
<auth> and parse the XML will break.

NACK to this approach. You need to remember that <auth> was part of the
disk and use it that way. (only for the top level image obviously, also
the snapshot operation needs to clear that flag, since it would change
if you merge the top layer snapshot back according to whether libvirtd
was restarted or not)
