Yeah. I have found that for message passing systems the tooling around multiple message types is more important in practice than optimizing for a single specific type. You can solve this with unions/tagged enums or some bespoke "message type metadata", but you HAVE to solve it some way. On the receiver end, you need to have a good story for routing different kinds of messages.
