Well, the issues of increased delay and greedy, unresponsive flows are,
to a certain extent, distinct.  One can image AQMs that are only
concerned with penalising unresponsive flows but don't do anything to
reduce buffer size when all flows are well-behaved.  Conversely, one can
imagine solving the buffer bloat problem on the assumption that all
flows are TCP-friendly.
