Sometimes you provide so much feedback on an Internet-Draft that the authors ask you to become a co-author. Such was the case with draft-ietf-mile-xmpp-grid, which defines a method for using XMPP to exchange information about security incidents (e.g., via the IODEF format) on a controlled-access network. The resulting standard (RFC 8600) is a rare example of what the IETF standards process document defines as an "Applicability Statement" (another recent example is RFC 8036). This is the 45th RFC I've authored or co-authored, which shockingly enough is one more than Vint Cerf - not that my contributions to the Internet are nearly as important as his!
