(My problem was not that draft expiry makes the process more complicated, but
that the chairs didn't notice the expiry and I can't blame them.)
Weeeeell, the system does send out automatic reminders (entitled "Expiration
Impending: draft-foo") to all authors and copied to the WG chairs.
So not noticing is almost as bad as continuing to post emails on this thread
without changing the subject line :-Z
Cheers,
Adrian
