Discussions were held with members of the IESG during the Spring 2008
IESG Retreat.
The outcome of those discussions was the suggestion that the OpenAFS
Foundation
make use of the RFC Editor's independent submission process as a forum
for publishing
future AFS standards.

During the workshop in Newark NJ the AFS community voiced concerns over the
standardization of the AFS protocols by the legal organization that
controls the
most popular implementation.

As a result of those discussions, Simon's proposal was drafted.

You are confusing the existence of an RFC with the output of an IETF
Working Group.
Not all RFCs are the result of the standardization process.   SSL, SSH
and XMPP are good
examples of what happens when an existing protocol is submitted for
standardization.

Lets put it this way.  If you want an IETF AFS Next Generation WG you
will need to
first hold a BOF that puts forth a formal charter of work items that the
WG is intended
to accomplish.  One of the pre-reqs for the BOF is going to be
documentation of the
existing Rx and AFS protocols.  We don't have such documentation.  We
will also have
to show where the resources are going to come from to perform the work
necessary
to complete the WG Charter.

Many of the members of the AFS mailing list have a long history of
participation in the
IETF as document editors, working group chairs, bof chairs, nomcom
members, and
application area and security area directorate members.  This is a
strong understanding
in this group of what the IETF is good at and what it is poor at.   

At the present time the IETF and AFS are not a particular good fit.
