Right, which means that for an NFS server, looking up a remote peer's
ATS record and checking against an exports file provides zero
security.  The remote peer can put any IP address it wants for itself
into the SA's database.

For ATS to be useful in this setting, the SA needs to know about ATS
records and have some way of checking the IP addresses they contain.
And configuring that seems likely to be quite painful.
