I don't think the underlying rules about downrefs have really changed since RFC 2026. I think you meant RFC 3967, and that was needed to clarify existing practice. But anyway, since the IESG approved RFC 6248, they must have decided it was OK at the time. Maybe there's an answer deep in the ietf-announce archive.
