As far as I'm aware, all anon=0 does is that it changes the default mapping of root access on NFS clients from uid=-2 to uid=0.
[That should be uid=65534 rather than uid=-2. Not the same thing these days!]
It may be true that this is the only thing anon= does in NetApp servers, and the na_exportfs man page implies as much, but this isn't the case on all NFS servers, so it's not exactly a good habit to get into.
In recent versions of Solaris, for example, the anon= value may be used for unauthenticated clients (AUTH_NONE, or an unsupported AUTH mode, with sec=none). One would not want to map such requests to root!
