I did the LC review of the same -16 version. I recon the issue spotted in Section 7 and acknowledged by the editor still needs to be fixed (either now by the document editor or then later by the RFC Editor). See the email exchange on the reflector: https://www.ietf.org/mail-archive/web/ops-dir/current/msg02273.html Other than the above, the document is in a good shape and ready for publication.
