The general idea is that once axles have been run on one side of the car, they need to stay there. There is a bunch more torque in the drive direction than when braking. This builds that stress you are talking about being done on purpose for torsion bars. Running the axles on the other side stresses the axle in the other direction which is not a good thing to do. Just because you can get away with it does not mean it is a good idea or something to be recommenced.

As far as CV joint wear...you are probably going to clean and inspect the CV joints so you can swap them from one axle to another. That will allow you use a different wear area and keep the axles on the same side of the car.
