I'd like to hear from the AD and chairs here. It seems to me that the
design I am suggesting is better, and if the primary argument is that the
editors don't want to make the change at this date, that's not very strong.
Conversely, I agree that this is a WG decision, so if you're telling me
that the WG considered this flavor and rejected it, then I think that's
reasonable and I'll remove my discuss.
