Would that increase the safety margin or more likely just put jack stands in your way?
As long as each stand is well below its rated capacity, it's hard to see the point of more IMO. Yeah, technically more would increase the safety margin, but with 4 reasonably-chosen stands the probability of a failure is so low in the first place that adding more would be meaningless. It'd be like having two front doors on your home or something.
When I pull wheels while a car is on stands, I do set them under the car as well when possible. Saves space in the garage while providing a backup if a stand fails or gets kicked out from under the car or something. Never needed that backup, or heard of anyone I know needing it, but it feels good to have I guess.
