I think there is a growing consensus among network engineers that ICANN and
a few at IETF (at least a few years ago) weren't 100% honest regarding how
DNS wildcards work.

I think we can all agree that the RFCs keep it vague enough that no one can
say for sure how wildcards work. This was I think a point of contention in
fact when ICANN took over from IANA in 1998.

Another good example of what I think qualifies as deception in regards to
DNS is ccTLD vs gTLD.

For instance, is .ms gTLD (Microsoft uses it) or ccTLD (for the island
nation of Montserrat). No one knows...
