I know as a kid long before I could drive, one time doing mopar brakes which had this stupid little rivet like metal piece that gets hammered in one shoe, I put it on the wrong one and left it that way. So the smaller lining had to go to the rear. When the next inspection came my Mom told me that the car needed rear brakes, only because the last set on one side was put on backwards. So it made a big difference in wear.
Remember when brake shoes had a core charge?
Young enough to learn ... too old to remember.
