I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. The document is ready. It's concise and does just what it's supposed to, nothing more. That's always good for security. The security considerations section reads, "This document should not affect the security of the Internet." I'd go even further and state that it in fact does not affect the security of the Internet. Documents published by the RFC editor's new model might, although they might affect it for the better as well as for the worse.
