It seems like there's an important distinction between (1) all 
intermediaries that look like a "proxy" when viewed as a black box, and 
(2) intermediaries that follow some protocols on the wire standardized 
in IETF specs.

(1) can follow any protocol internally by private agreement (or just be 
a unilateral intercept by corruption of protocols, like CA and/or DNS 
spoofing.) But it still may speak standard HTTP on the outer interfaces.

One motive for trying to standardize more about proxies is to surface 
and specify legitimate use cases. ("Legitimate" as defined by the people 
owning the systems and networks involved.)
