Sod the composer- it's not up to him. That's what tradition- a process involving natural selection - does. He has two choices: (1) insist that no one plays it except how he approves, and uses the law to enforce his preferences (2) let it develop, in which case his preferences are just one set among many.

If choice (1), he'll spend a fortune to ensure it's forgotten within 20 years.

If choice (2), anything could happen.
