Of I read that and it's overall convincing enough for me. I do also wonder about the point raised there about doing surveys of doh deployments - as one poster (willscott) said though, I'm not sure if I think enabling that is a good thing or not. (The downside being that censors discover deployments too.) I'd not argue that's reason enough to retain well-known in the draft.
