Well I'm not really sure, but I said you could I didn't say use it.
But anyways it can be added to new patches but yeh I guess we carnt use it judging by it will add to all users even if they aren't new.
Sorry to waste a comment.
@Paladox: If you write that "we could user Herald to do this", you imply that it is technically possible. Hence I asked you how exactly it is possible. If you do not know whether it is possible, please investigate first before adding any comments implying that it is technically possible. (Or make it clear after your investigation that Herald could be used after additional code changes.) Thanks.
