I hate to belabour a point, but if the client interacts directly
with the name service (rather than through an NFSv4 server intermediary)
then there is no new "root server authorization" problem to solve.

Those clients that are already using a secure name service (e.g. LDAP or
Active Directory) have previously authenticated the provider of the service
and rely on it to provide lots of other enterprise data.

Data for a global filesystem name service is just an add-on.
