This is not so crazy - this was exactly the progression in screw drives. First came slotted screws (2-fold rotational symmetry), then Phillips/posidrive/Robertson (4-fold), and now Torx (6-fold). Going back to slotted now is actually irritating.

Of course the constraints and trade-offs are very different... still it would be a piece of cake to plug them in on the backside of a box with your eyes closed.
