Joe - I don't see that this document fundamentally requires TCP port support for DHCP operation as described in RFC 2131.  This document describes a protocol that is closely related to but independent of RFC 2131, and a server based on RFC 2131 can perform all the DHCP functions in RFC 2131 without considering this document.  So, I can see your point but I disagree that this document updates RFC 2131.

Regardless, that too would be a reason for this as an update to 2131. It's only NOT an update if this service is independent, IMO, and it doesn't read that way to me.

There are other RFCs that add new, independent functions to DHCP without making changes to RFC 2131 (e.g., RFC 4388), which are not listed as updating RFC 2131.
