Re: [saag] [Sam Hartman] draft-harris-ssh-arcfour-fixes-02: informational or proposed?

[Jeffrey Altman <[e-mail]>]

My personal opinion is that if there is a protocol that has been widely
deployed but which for whatever reason the IETF does not want to
encourage its adoption, the RFC should be published immediately as
HISTORIC.
