I have wondered the same thing about that and a few other muscles. It all comes down to what your individual needs are. So pump sets and isolation movements in loading sets are a good place to put rest delts. For example today I did my all out set of shoulder press then moved to a reverse pec dec while maintaining scapula protraction so that it's all rear delts. I would say they are a minor weakness of mine so I prioritized them here. Could I use more side delt too? Yeah of course but if I don't have balance at a smaller size then I'll look terrible. We could all be bigger. Just comes down to the balance and symmetry of the size you're at. I know some guys in my weight class (small) but look insane due to the symmetry. I think myself as a smaller guy and guys like me are too focused on just being as big as possible.
