ChangeTracking like a greate feture but it seems to be transient for serialized object. Is it possible to somehow enable change tracking on serialized objects so only changes made to a given object are pesisted?

The change tracking is not serialized because it is a way to keep the changes recorded in the persistence unit - serialization breaks the link to the persistence unit, so the entities need to be merged to be reassociated anyway. Only changes made to the given objects will be persisted when you merge those detached, serialized instances back into the persistence unit, and the managed instance returned from em.merge will have change tracking enabled.
