That's a fair characterisation, yes.

In fact, even for middleboxes, the "flow isolation" semantics of FQ have the most impact on reducing inter-flow induced latency.  The "codel" part (AQM) helps with intra-flow latency, which is usually much less important once flow isolation is in place, but is still worth having.
