More generally, the topic of feedback loops came up in the 2015-08-05
meeting [3,4] (after 26:02 in the video), and the consensus was to
start discussion anything that seemed worth discussion on the mailing
list ("conversations and discussions should be on
dev@opencontainers.org mailing-list first, conversations and
discussions should be on dev@opencontainers.org" [3]).  That doesn't
speak to agenda-formation specifically, but it makes an official
policy of discussing most things on the mailing list, and the two
posts I quote above extend that general approach to agenda formation.

While touching this paragraph, I also re-wrapped it to match
README.md#markdown-style.
