Fred, my reasoning for not using shared neutrals is that a thoughtful weekend warrior (even one with some electrical experience) won't overfuse, but may move breakers around without understanding that it's causing a fire hazard. Of course, a fool with a screwdriver can kill himself or burn his house down.
Do you really try to sell a sub-panel on a one circuit job when there are four to eight available spaces in the distribution panel??? I think that would be a tough sell. I'd have a hard time keeping a straight face telling the homeowner they needed it.
