If you want to add a component to magazines, backpacks, and maybe weapons or magazines there are multiple unrelated base prefabs being used. But no common denominator like Equipment_Base. This makes it a huge pain to do advanced modding because I need to override countless prefabs with no guarantee that future additions might not again get a new unrelated base class.

This is one of the worst cases. They are all ammo, but none of the ammo types share anything ...

I get that not everything belongs together and I would not make a base prefab that is shared by a tree and a compass, but I think it would make sense to introduce something for Equipment (anything a player could equip, take to hands or otherwise store in his inventory). If one base prefab is combining too much, then please at least try to combine some larger groups like Ammo.
