It is until you have very stateful filesystems. Then you have to have
persistent storage somewhere that tells you what the heck you were
thinking of last time you created a filehandle. You end up doing a table
lookup, dispatch, and possibly a copy on every incoming packet. You never
know when a client has finished with a file.

All of the problems with the user-space NFS server should be sufficient
evidence that NFS is limited at best as an abstraction for arbitrary
filesystems.
