We have also included the change here: Original: It would assist with the progress toward a simpler, more coherent system of MPLS data encapsulation if the use a PSH for non-IP payloads encapsulated in MPLS was obsoleted. Current: Section 2 of [RFC4385] suggests the use of a PSH solely for the purpose of avoiding IP ECMP treatment of non-IP payloads encapsulated in MPLS. Obsoleting this use of a PSH would assist with the progress toward a simpler, more coherent system of MPLS data encapsulation. (Other uses of a PSH may still be valid.)
