it is even worse than that. I remember the very IETF meeting when this was
presented and the then chair of the IAB, IIRC, tried to convince the
proponents to reconsider.  Some of us went out to initiate some DNS
registrations ("went out" means we couldn't just use our wireless laptops,
back in the last century).

Unfortunately this is a reocurring mikstake, grep for "_nfsv4idmapdomain" in
your DNS logs.
