Why would that be needed, especially for people that properly setup their qdisc ? Maybe they do not want to force fq on all devices like tun or taps ;) Also we intend to provide a fallback in case FQ is not in the qdisc chain : Some routers admins really want fq_codel (or whatever qdisc) TCP will handle the pacing itself, at a small cost for the ones that hate fq.
