Ron, This statement is incorrect. As already explained in the mailer, the SID identifies the packet processing that must be done on egress. The IPv6 No Next Header indicates that there is no further Internet Protocol header to be processed before the encapsulated packet.
Multiple options were discussed on the list with no clear consensus. The authors suggest keeping NH=59 for this use. Note that SRv6 uses also the IPv6 No Next Header (59) for other non-IP payloads different from ethernet (e.g. Unstructured PDUs -draft-ietf-dmm-srv6-mobile-uplane-05) Cheers, Pablo.
