I generally agree with Geoff Huston's thoughts on this subject

Mirror zones (validated zone transfers) fall on the wrong side of the
cost/benefit equation for me. But I might change my mind if there were
better security for unauthenticated records (NS and glue), e.g.

* xfer-over-TLS - I'm really looking forward to support for authenticated
  server / anonymous client for zone transfers: nice for local root zones
  and cross-campus zone distribution.

* zone digests - interesting for end-to-end verification but maybe too

Note that @diffroot does not tweet about changes to glue addresses which
happen a lot more frequently than NS and DS changes.
