other than one proviso and one misstatement, i agree with this.

the proviso is, RFC 7706 is also completely unsuitable for non-hardcore or non-
experienced or non-protocol-geeks; and both approaches are appropriate only for closed 
internal networks where the configuration is controlled by a single administration.

the misstatement is, dnssec's purpose is not defeated, because iana's signatures are 
checked before the zone is accepted, and new signatures are added using local keys 
before publication.

for my many-vm's laptop environment, running on a loopback isn't a solution.
