So, I think we have to be careful about what we consider part of
the IETF mission, if we cannot get basic agreement upon the implications
of the mission statement.

The past is the past, I don't want to revisit the past.  What I want
to do is to look forward.  We should have flexibility in terms of
how to decide what the IETF can do, what it can't do and what it
should (or shouldn't do).  I think we cannot make a blanket statement
in the mission that covers this.
