It seems we want to obstruct users from creating the object - that means we need to disable users to new/extend it. If I understand it correctly, using the interface is a suitable way. Maybe we can have introduce a new annotation to explicitly remind users not to implement the interface. If we are in Java 17, the annotation can be replaced by sealed keyword. Best, Chia-Ping
