This is a kind of strange incentive - the end-points can get to even
better performance (in a network dominated by TCP) by being agressive and
ignoring congestion control whatsoever.

Since this didn't happen (yet?) it does not appear strongly attractive to
the actual users, their e2e performance being heavily dominated by
capacities of servers and tail circuits.
