Some traffic analysis is still possible based on just message originator. If I
see a message from A, and then soon see messages from B and C, then I can
perhaps assume they are collaborating. If I A's message is significantly
larger then the other two, then perhaps they're taking some kind of vote.
So while it's a neat hack, I think the claims are overstated.
