This is a good argument for trying to figure out how to extend the CT
model into the DNSSEC space, as was proposed by Dacheng Zhang at the
trans wg earlier this month.

  https://tools.ietf.org/html/draft-zhang-ct-dnssec-trans

That proposal had some serious flaws, but anyone interested in doing
this kind of monitoring work of centralized/hierarchical infrastructure
should take a look and suggest improvements.
