[hibernate-dev] Dropping "Serializable" requirement for IDs ?

Hi all, today creating a unit test I was greeted by this "old friend": shall we get rid of this requirement? It's just an inconvenience for end users to have to remember this marker, as far as I know we don't really need this anymore. I realise some code might still be needing this, but we probably can do better by not actually serializing it with the default platform serializer? Just an idea for a potential 6.0 improvement.. Thanks, Sanne
