FWIW, IMO this is all make-work. IANA pointers to the old doc should turn up "obsoleted by" notices. That ought to be enough to trigger the user to follow the right path. Otherwise, IMO, this doc should basically say "IANA pointers should be updated as deemed useful". In some cases, there's a benefit, but not in all cases. E.g., we have docs that obsolete protocols but IANA still keeps a pointer to the codepoint. I don't want the new pointer to be to the doc that obsoletes them; I would want the pointer to be to the original spec. I.e., remember that "obsoleted by" can also effectively mean "moved to Historic by". I.e., nobody looking at TCP-MD5 should necessarily get the RFC to TCP-AO. And there's no way to know what's in active use *somewhere*. I'd prefer to trust the author to do the right thing that to engineer this document with an algorithm.
