You're probably thinking of [1] in which Peff referenced an earlier email[2] in which he stated his thoughts on the subject. The result of [1] was that git-workree was changed[3] to use stderr rather than stdout for its chatty messages, and (significant to this discussion) CodingGuidelines was updated[4] to cover this topic, so we can now refer people to CodingGuidelines.
