I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG.  These comments were written primarily for the benefit of the security area directors.  Document editors and WG chairs should treat these comments just like any other last call comments.

This document registers three new error messages for an http server to report problems with an http request. I find it unsettling the amount of text people must generate (and so many other people must review) to accomplish such a simple task, but it would be unfair to blame the authors who are victims of the system our community has developed. I wonder when these documents will start being constructed by AI.

The security considerations section is well written though obvious and therefore not terribly useful.

I found no nits.

I sure hope we can ship this thing without too many more rounds of revisions.
