I had hoped, I had made sufficiently clear that I was mentioning these options for completeness sake, only (and partly for the joke).
But yes, I have indeed used the second before. If a project is only complex enough and the hierarchy in OM gets deep enough, there is a, admittedly rare, use case. BUT even then you can reach similar effect with dragging a parenting Null to the HUD. Or by using layers to hide parts of the hierarchy in OM. Many roads leading to Rome, I guess.
