    Helper method to create a compatibility classic single file checkpoint file for this table.

    Helper method to create a compatibility classic single file checkpoint file for this table. This is needed so that any legacy reader which do not understand V2CheckpointTableFeature could read the legacy classic checkpoint file and fail gracefully with Protocol requirement failure.
