I kind of disagree. I might end up whipping my head around every time I need to avoid a hazard in the road that the riders behind me, who I don't know are there, can't see. I would say that if you are giving plenty of space, then no call out is needed, but if you have to pass closely or there are a bunch of people behind you, then it is best to call out.
