Hi Kory, I haven't lost track of this, I'll try to have a look as soon as I can. For the record, I still don't think this is a great idea. I'd rather have people follow the design docs. I understand the acceptance capsule feels 'weird', but there was a good reason for it. There's a PR with an update to the spec, which makes the acceptance substantially easier now that all the ecosystem parts are in place [0[
