Network was dynamic and configurable way before cgroup came along and thus has its own naming, classification and control schemems, so it makes sense for cgroup to just hook into the existing facilities. So, it's partially historical but that's not the whole story. cgroup membership is but a tiny portion of how network traffic is shaped and routed - e.g. the destination address, port or packet type are factors too. cgroup can't slurp in all those. It has to be one part of the pieces that the networking stack considers.
