This is the significance of the specification not being on the standards track.

This document defines the bindings of the various Network File System (NFS) versions to the Remote Direct Memory Access (RDMA) operations supported by the RPC/RDMA transport protocol. It describes the use of direct data placement by means of server-initiated RDMA operations into client-supplied buffers for implementations of NFS versions 2, 3, 4, and 4.1 over such an RDMA transport.

This document describes the specifications for a server of WebNFS clients. WebNFS extends the semantics of versions 2 and 3 of the NFS protocols to allow clients to obtain filehandles more easily, without recourse to the portmap or MOUNT protocols. In removing the need for these protocols, WebNFS clients see benefits in faster response to requests, easy transit of firewalls and better server scalability This description is provided to facilitate compatible implementations of WebNFS servers.

This document describes a lightweight binding mechanism that allows NFS clients to obtain service from WebNFS-enabled servers with a minimum of protocol overhead. In removing this overhead, WebNFS clients see benefits in faster response to requests, easy transit of packet filter firewalls and TCP-based proxies, and better server scalability.
