That's what PRACK does in *most* of the use cases. I think having PRACK carry an updated offer sdp was allowed/required for precondition call flow. So in that sense what happens to 18x retransmission when PRACK's offer is rejected is not a widely used case. But Prack can be rejected for other reasons, and I think handling in UAC & UAS of a Prack error should be same, no matter what the cause of error is.
