Nope. The paced flow puts less strain on the buffer (and hooray for that),
which is a win no matter if the buffer is contended or not.

fq_codel doesn't give any specific incentive to do pacing. In fact, if
absolutely all devices on your path would use fq_codel and have adequate
buffers, I believe pacing would be largely a no-op.
