It is a difficult model to follow when writing a document if one is required to explain everything that is NOT an issue. The new statement in the draft says: "No new security issues are introduced by the protocol extensions defined inn this document. Security concerns for IS-IS are addressed in [RFC5304] and [RFC5310]." I believe this is both accurate and complete - and my comments above explain why.
