Acee,
I think you are saying you prefer to remove the “updates”. Is that
right? It was a little confusing given the reply chain.
(I’ve already given my opinion but said I’m not going to go to the mat
over it.)

That we be my preference as well. We’ve had several discussions on
what constitutes “update” and I believe that the consensus was that
a document isn’t “updated” unless the current behavior is changed.
If we’ve done our jobs, protocols are designed to be extended and
these extensions shouldn’t constitute updates.
Thanks,
Acee

Hi!
As John mentioned, "Since for better or worse we don’t have a firm
definition of when we do, and don’t, use “updates”, it comes down to
a matter of personal taste in the end.”
I rather you leave it in.
Thanks!
Alvaro.

John, Alvaro,
do we have a consensus whether we need the update to RFC 7370 or
not?
thanks,
