Yes, well, I do also like the E2E principle of not making too many
decisions within the network, instead letting the endpoints sort it out.
For me, the fight against bufferbloat is mostly about restoring the
assumptions that it has eroded (i.e. "packet loss is not to be feared,
but on the contrary is an important indicator that we're hitting
congestion"). I'd really rather prefer the network itself to be fairly
dumb...

Hehe, quite. That is both fascinating and frustrating! :)
