I think that the 2 things have to be carried on independently, because
the end-to-end solutions are not a real solution to the bufferbloat.
The problem is that one cannot make sure that end users will act
fairly, by adjusting their sending rate.
The only way to do this is dropping packets, so that they are obliged
to send again.
If the bottleneck is on a router that is not in your house, you can
enable any congestion control solution in your nodes and you will in
no way experience improved RTT, if other flows from other users do not
act fairly and pass through the same bottleneck.

Am I wrong with my reasoning?
