An interesting point, but probably one better made to ICANN. Try
icann(_at_)icann(_dot_)org(_dot_) Since its not a standards or protocol
probably not an IETF issue.
I disagree that this is not a protocol issue, as it certainly affects
operation of protocols. There are probably issues for the DNS protocols
also - if nothing else it may be that some claification of the
specification is needed.
It can be quite reasonable to make wildcard assertions about RRs that
are all within the same administrative domain, but arguably this
condition is not met for the COM or NET zones.
