That surplus is a deep well but it's not infinite. They have to cut it out eventually, and if your theory is correct then they'll cut the military aid to Ukraine sooner than later because it wouldn't make sense to send them the more modern equipment once all the stockpiled rusty weapons run out.
I still think that the slow trickle of many different types of equipment is mostly about seeing what modern Russian equipment does to them. A big bloody R&D exercise.
