Re: Working Group Last Call: Mnemonic to Proposed Standard

(Wearing my Standards Monger hat)

RFCs that are labeled Informational or Experimental are published by
the RFC editor, primarily at his/her discretion but after coordination
with the IESG.  The coordination is to ensure that the document in
question does not collide with IETF work-in-progress, or the like.

I believe that the primary basis for having a WG recommend an
Informational or Experimental status is to make an explicit statement
that a spec is *not* intended for the standards track.
