Note that a quantum mechanical pendulum gives you a central spot with a blur each side. Not common in LF situations.

My feeling is that even casual viewers of photography are very good at interpreting motion blur. It's a natural way to add gesture to a static frame, and although there is a danger of it becoming a schtick, it's a useful tool to have ready.

I sometimes let the wind shake the whole camera. The effects can be a bit centered with a wide angle (where angular blur gets bigger towards the edges) but I mostly use long lenses where the effect is even across the frame.
