The latter would seem to be avoidable by making sure that *DNS resolution
of bare TLDs always returns NXDOMAIN*.

Not  NXDOMAIN.    When  TLD.  is looked up,  they should always return NOERROR.

And yield, either   (1)  the NS records for the TLD,  for QTYPE NS or 'ANY'

For other queries   TLD.  should return NOERROR  with  Zero RRs in the
answer   (Empty response).


A NXDOMAIN response would be declaring that the TLD does not exist.
