We've actually got several of them, starting with SOCKS (which could have been extended), continuing through RSIP, on to midcom and SIMCO. Note that "midcom" was so named under the assumption that whatever was done would be extensible to other sorts of middleboxes than firewalls and NATs We could spend an awful lot of time talking about why none of them has caught on, but I think it's fair to say that that failure has not been caused by a perceived lack of generality.
