It probably wouldn't *need* to for most purposes.  The major reason I
can think of offhand is that that's the easiest way to get permissions
checking properly enforced.

If you trust all processes on the NFS server, and don't need to worry
about races between the NFS server and other userland processes on the
machine, a userland server running as root could probably do the job.
Or at least I'd guess so; I did it for NFSv3 back in the '90s, but I
haven't looked at NFSv4 enough to know details of the differences.
