The explanations added to section 4.16.1 "PSP: Penultimate Segment Pop of the SRH" certainly help. However, there is still no explanation of how this section is reconciled with RFC 8200. Whether the reader agrees with that reconciliation or not is a separate matter, but I fail to see how this draft could progress to IETF Last Call without such an explanation.

See https://mailarchive.ietf.org/arch/msg/spring/Xrcclo0s4pnug9upG9rUinYMv1I/
