	I similarly suspect it would be.

	I would be interested in some more generalized transparency reporting
capabilities in the DNS.  It's easy to see who gave out certificates for
*.nether.net in certificate transparency logs, it's not easy to find out who
gave out puck.nether.net as something other than 2001:418:3f4::5 or
for example.

	I can find some of this in various passive dns databases but they're
generally not as public :-)
