You're correct in that it's obsoleted and History-Info is the solution adopted by IETF but the Diversion header is far from obsolete in practice as it's used by major IP telephony system providers like Broadsoft and Sonus and probably quite a few more. In addition, Kamailio has the Diversion module specifically for this header.
