That's argueable I guess. Likely or not, it doesn't make sense to

trivial to just look at the cgroup of the task directly.

Isn't a very large fraction of outgoing network traffic driven from
net_tx_action(), which doesn't execute in the context of the sending
process? Or am I missing something?

You claimed "In the most common case, the packet is not queued before
it hits the qdisc so this takes away a lot of complexity and is very
fast but should still be sufficient.". But is that really true on a
system where the network is busy? (Which is after all exactly the case
where you care about accurate traffic accounting/policing)
