Yes, I think this was introduced in Release 7. However, it would
require the use of "PPP" pdp type in CGDCONT, not "IP". Also, for EPS
contexts I don't believe that "PPP" type is possible (nor wanted, as
you'd fry your CPU keeping up with the high-bandwidth connection).
Probably a legacy feature that might still be used in very narrow
circumstances. I've certainly never seen it used in practice.

True. But I'm probably missing your point. PPP packet compression is
still an optional protocol feature, so it should not preclude
interoperability.
