Re: [BEHAVE] [Errata Held for Document Update] RFC5389 (3737)

Disclaimer: I wasn't on the IAB at the time, nor was I active in Behave at the time.

My opinion: The status "Hold for Document Update" is probably correct given the
guidelines for errata processing, but I think the proposed "corrected" text is wrong.
The original text is not inherently flawed, just potentially confusing,
but not in a way that would affect any implementation.

What RFC 3484 said was specifically:
  "the IAB believes the following considerations must be explicitly addressed in
   any proposal"

The use of "must" above is far stronger than the "corrected" text's use of
"suggested" (or even "recommended") which is why I believe the correct text is wrong.
The potential confusion in the original text is just that what the IAB believes/believed is
must be done, is enforced (or not) by the IESG, so if anything is mandated per se, 
it's mandated by the IESG.

A more accurate corrected text would read:

> The IAB has stated that protocols developed for this purpose must document a
> specific set of considerations.
