Status of draft-christey-wysopal-vuln-disclosure-00.txt

At some point, the authors of this IETF draft have officially
withdrawn it, but this document is still being referenced a lot,
sometimes in contexts which might lead inexperienced readers to
believe that this draft is supported by the IETF.  It's even expired.

What's the status of the document, as far as the IETF is concerned?
Will it remain in the IETF archives forever?  Has the withdrawal been
withdrawn?
