This LGTM; I'm not aware of any major objections to moving forwards with the new format, so IMO we're alright to land this and work towards test conversions. We can, after all, revise the format if problems crop up.

(Not sure what the convention is on  landing / approving while @phyBrackets still has a request-changes bit on the PR?)
