I think the notion of a strong containment guarantee to participating 
networks that you mention is a bit extreme in contrast to just reducing 
the likelihood or severity of issues. There has been a lot of congestion 
control experimentation on Internet paths that strong containment has 
not been expected of.

I think the sense of the working group has been to take an approach of 
collecting and recommending reasonable measures to identify and avoid 
issues when experimenting with L4S.  This is mainly in Section 4 of the 
ops draft right now.  I have not understood the general working group 
direction to be asking for strong containment guarantees though, and I 
don't think that needs to be a goal.
