I'm having a hard time coming up with a crisp answer to this.

>From a security perspective, failing to do either of these doesn't create
any sort of security exposure, so neither is justified.

necessary for robustness and operator sanity (i.e., the complete picture is
recorded which enables debugging), so both are justified.

just fine if you make the shortcut Doug is proposing, so the first SHOULD
is probably apt but the MUST is moot because it doesn't change
interoperability.

I guess it depends on what we think the priority is.
