Hi Claus I agree the component should take responsible of copy the In message headers into Out message headers. we could provides util class to do that copy thing in camel-core. But the component should also need to make sure some of the out message header value which is copied from in message should be overrided according components logical.
Such as the response context in camel-cxf component message header, it should be overrided when the camel-cxf producer get the response from actual web services.
