Abstract
This memo documents an experiment to review and classify Proposed
Standards as not reflecting documented practice within the world
today. The results identify a set of documents that were marked as
Proposed Standards that are now reclassified as Historic.

1. Introduction and History
RFC 2026, and RFC 1602 before it, specified timelines for review of
immature (draft or proposed) standards. The purpose of such review
was to determine whether such documents should be advanced, retired,
or developed further [1].

RFC 4450 Cruft Removal March 2006
This procedure has never been followed in the history of the IETF.
Since this procedure has not been followed, members of the community
have suggested that the retiring of a document to Historic is a
significant event, which should be justified carefully -- leading to
the production of documents such as RFC 2556 (OSI Connectionless
Transport Services on top of UDP Applicability Statement for Historic
Status) and RFC 3166 (Request to Move RFC 1403 to Historic Status).
Such documents require significant time and effort on the part of
authors, area directors, and the RFC Editor.
2. Bulk Decommissioning Procedure
From the Fall of 2004 through the Spring of 2005, the authors
conducted an experiment to determine how many Proposed Standards
could be considered obsolete. The experiment was operated as
follows:
o Identify a group of documents that are standards.
o Assume by default that each document will be retired.
o Create a mailing list for discussion with a policy of open access.
o Allow any document to be removed from the list of those to be
retired for virtually any reason, so long as a reason is provided.
o Present the list to the working group, IETF, and IESG for review.
o Revise list based on comments.
o Write up results.
The initial intent of the authors was to present a list of documents
to be reclassified as Historic. The NEWTRK working group supported
this view. The IESG, and the IETF as a community, makes the final
decision. We will discuss this further below.
3. Input, Mailing list, Output, and Observations
We started with our initial document set being all RFCs with numbers
less than 2000 and a status of Proposed Standard. The input we used,
starting November 25, 2004, can be found in Appendix A. There were
some 125 documents in all.
A mailing list, old-standards@alvestrand.no, was created to discuss
and remove candidates from this list. A call for participation was
issued to the IETF-Announce list on or around the November 15, 2004.
There were 29 members of the mailing list. Approximately 244
messages were sent to the list. People were encouraged to consider
the question of whether or not an implementer would either write a
new implementation or maintain an existing one.

RFC 4450 Cruft Removal March 2006
After some months the list of documents to be considered was reduced
considerably. This list was then forwarded to the IETF discussion
list on December 16, 2004, and to the NEWTRK working group list for
wider review.
During review, RFCs 1518 and 1519 were removed, based on the fact
that work is ongoing to revise them. Similarly, RFCs 1381, 1382,
