i.o.w: DNSSEC doesn't sign delegations and thus the "delegation" of the "."
by the root.hints files of the world dosn't require it, either.

The more practical problem is that as long as the root servers' names
reside within root-servers.net, even a signed priming response isn't
self contained and complicates matters.

contains part of that discussion and reflects the results of the results
discussion of the IETF DNSOP WG on this topic.
Followup to <dnsop at ietf.org>, please.
