Well, they "advance" from Working Draft to Working Draft and then it's
too late to make changes before there is a "Call for Implementations" as
the implementations have already been shipping for years. The Last Call
is meant to avoid that, providing an opportunity to build a consensus
even with people and organizations that cannot follow the day-to-day
working group and implementation progress to prioritize their reviews.
Which the Last Calls relevant to this thread obviously do not provide.
