When the NFSv4 server was coded, I believed that the specification authors
did not want NFSv4 servers to require a client to use a reserved port#.
However, recently it has been noted that the Linux NFSv4 server does support
a check for a reserved port#.
Since both the FreeBSD and Linux NFSv4 clients use a reserved port# by
default, enabling vfs.nfsd.nfs_privport to require a reserved port# for
NFSv4 the same as it does for NFSv2, 3 seems reasonable.
The only case where this could cause a POLA violation is a FreeBSD NFSv4
server with vfs.nfsd.nfs_privport set, but with NFSv4 clients doing mounts
without using a reserved port# (< 1024).
