This sort of constraint is a safe guard against run away working group
chairs attempting to ram through changes by silencing people who have
not read the latest draft that came out while people were traveling to
The issue is not the reasonableness of the reason for wanting to do it, but
rather the unreasonableness of imposing it on all working groups.
Fear that some groups might stray is not a good reason for treating all
groups with that fear.
The IETF used to be quite flexible, permitting many styles of legitimate
working group operation. Instead we have let fear of runaway working groups
justify more and more burdens. So rather than being a venue that can
permit minimal overhead -- where legitimate -- we have become a venue with
high overhead for all efforts.
