> Today, ON_TIME panes are emitted whether or not they are empty. We had decided that for final panes the user would want to control this behavior, to control data volume. But for ON_TIME panes no such control exists. The rationale is perhaps that the ON_TIME pane is a fundamental result that should not be elided. To be considered: whether this is what we want.
