Excellent. Thanks Ole.

If it's a *new* substantive technical comment, I absolutely agree, that 
should go back to the WG list. However, if this is an old topic that the 
WG has already come to a conclusion on, bringing it back to the list is 
not useful unless something has changed; that just becomes a "pile on" 
session. That's why I suggested Ole summarize the issue first, and that 
should be copied to the IETF list. That way we can see whether the issue 
is "The WG missed this important aspect of the issue" (which should go 
back to the WG to discuss once it's properly formulated) or "The chair 
misevaluated the consensus" (which should probably be handled by you and 
the chair). Either way, we agree that a protracted rehash of the topic 
on the IETF list is not the right choice.
