Reading along, it strikes me there is a huge point implicit in your last sentence. I first thought of attribution as being able to tell what a particular allocated object is being used for. That requires state per object. However, you are talking about maintaining a count of objects by user. That is vastly cheaper, and likely 90%+ as useful. SO there is "object attribution" and "total usage attribution".
