I think this is looking good. A few (slightly opinionated) grammar things.

@manics @JimMadge : If you're happy with the discussion points above, can you resolve them? If not, can you suggest a change you'd like to see? Should this PR stay up for comment for the full 7 days or is it ready to merge?

[JimMadge]

I've changed my review as I don't see any reason to block this.

My take on the lazy consensus model was that 7 days with no objections is approval, but that isn't to say things can't be approved before 7 days. It might be worth giving this some more time for others to look at?
