When it comes to hand signals and more broadly communication with other drivers I have found the more the better as communication reduces ambiguity which reduces stress of those one is sharing the road with.
I don't think I've missed the point at all, I just balance all considerations including efficiency and courtesy with other safety concerns differently than you. I'm also not clipped in, so I'm a lot more relaxed about the idea of putting my foot down, and you're probably more concerned with pulling off a rolling "stop". I'm actually more concerned with my courtesy towards pedestrians than towards drivers.
Frankly, as a driver, I know what things cyclists do that annoy me. "Not signalling stops" and "not signalling right hand turns" aren't anywhere on that list. I approach every 4-way stop intersection as if I expect the other person to roll the stop sign and stop my car as required by law.
