I'm a bit worried that the way it is implemented now, if we turn it on
by default we risk activating conntrack even when it was otherwise
disabled... That would be a bad side effect, so I think it's better to
be safe and leave it for userspace to enable (which, again, we could do
by default in sqm-scripts).
