[BB] I'd agree that this is a good pair of generalizations to be 
addressed by the WG. Do you envisage writing guidelines for implementers 
of the lower layer algos to be in scope, or only guidelines for 
implementers of end-system algos? My vote would be for both.

[BB] Were you prompted to include this by some current implementation 
attempting this?

I don't think it belongs in a list of things the WG is chartered to work 
on though (a charter isn't normally a place where you would find a list 
of things to /not/ do). I don't think it would even need to be in the 
ICCRG charter - we don't need any (more) research to prove that this 
would cause congestion collapse. It is surely just sthg that the 
proposed RFC5330bis would say is highly dangerous, explain why, and say 
"thou SHALT NOT".
