Let me ask differently: say a class A { B b; // detachable and serialized="true"
}
When you store an instance of A with a ref to B, B is serialized with detached
flags, but there is no utility of adding detached flags during serialization of
B because its purpose is to store in the database. So IMO, we should not add
detached flags in serialized stored instances.
So, it is a waste of space in the database.
