I don't think we need a CfC to publish a WD, right? We should just publish it, and then open a CfC on the plan to move to 2nd edition with these changes incorporated, and asking if there are other changes we should include before we move ahead.

If there are no other changes people come up with, we make a CR in a few weeks. If there are, we need to get them reviewed - if they make sense we have a WD and then a CfC on whether to take that to Rec.

A couple of weeks for the CfC to give people time to check, plus a few days delay for publishing, seems a reasonable buffer for review, and we should be clear that if people need more time to check they should ask for it during the initial period of the CfC.
