Re: Cross-area review (was Meeting rotation)

We’ve got the existence proof of the counter example in SIP. I cannot count how 
many times I heard, “Yes, I know foo is broken, but it has been in 2543bis-02 
and now we are at 2543bis-06 and we could not possibly make a change because so 
many vendors implemented to bis-02.” Egad! We could not change what was in an 
Internet *Draft*??? Imagine the pushback to changing an RFC.

For better or worse, I have a lot of trouble believing that

Mumble. I’m not sure. I seem to recall many cases
where somebody has to explain to $vendor that
things have changed and they can’t do what
they wanted to do. In more cases than just
draft changes.

Results of course vary. But, ultimately it is an IETF
community decision on what a working group does.
Do they weigh the existing implementation base
or some other factors more? You or me might
disagree with some of those decisions… perhaps
on good grounds. I’m not sure the overall situation
would be better if we somehow got to override
the wg opinions. (Except of course on clear
issues that fulfil Discuss criteria.)
