This is going to touch on another aspect I have been thinking about “time” and “role”.
A model is developed in time measure from the first idea through class blitz through adjustments through translation and deployment. Model elements serve different roles. Maybe some model element serve to clarify. And maybe some clarifying model element only serve this role early in the time line described.
So, I wonder if some model element might be used early in the time line and then eliminated when their role has been served as is no longer useful?
