mass and weight serve different functions. It is a nuisance if you have many load cases. They therefore neither exhibit membrane deformation nor report the associated forces, whereas semi-rigid diaphragms simulate actual in-plane stiffness properties and behavior. The same is true if you import a model with duplicates - you can set the option to merge or not.
