RFC 6919: Further Key Words for Use in RFCs to Indicate Requirement Levels

RFC 2119 defines a standard set of key words for describing requirements of a specification. Many IETF documents have found that these words cannot accurately capture the nuanced requirements of their specification. This document defines additional key words that can be used to address alternative requirements scenarios. Authors who follow these guidelines should incorporate this phrase near the beginning of their document: The key words "MUST (BUT WE KNOW YOU WON\'T)", "SHOULD CONSIDER", "REALLY SHOULD NOT", "OUGHT TO", "WOULD PROBABLY", "MAY WISH TO", "COULD", "POSSIBLE", and "MIGHT" in this document are to be interpreted as described in RFC 6919.

@anticomposite @simontatham tfw the IETF thought of your shitpost even before you did.
@can @anticomposite shitpost it may have been, but it's been a pretty popular one so far. Guess nobody else had seen RFC 6919 either!
@simontatham @anticomposite definitely funny! The fact that there's an actual RFC for it makes it even funnier imo

@simontatham @can @anticomposite

You've got some good ones that are still missing. Please submit a new rfc.

@can
What I've always liked about RFC6919 is that for *every* so called "key word" it "standardises" it provides an actual example from an actual non-humorous RFC which uses that exact phrase.

Making fun of yourself the right way.
@anticomposite @simontatham

@wouter I had only read the abstract, but thanks to your note I had to read the whole thing. It's brilliant.

@anticomposite @simontatham @can

My favorite reference:

The phrase "MIGHT" conveys a requirement in an intentionally stealthy fashion, to facilitate product differentiation (cf. "COULD" above).

For example: "In the case of audio and different "m" lines for different codecs, an implementation might decide to act as a mixer with the different incoming RTP sessions, which is the correct behavior."

I just adore that passive aggressive "... which is the correct behavior" and would love to hear the anecdote for why the editor snuck that in there and how many chairs were thrown during the meeting.
