As a service to the community, let me explain:

Essentially, and for some reason, they seem to be meaning to circumvent 
specs and processes.

One of their last inventions has been to pretend that IPv6 allows EH 
insertion/deletion en-route, based on their reading of RFC8200. Based on 
a curious interpretation of the text, they claim that each waypoint 
(intermmediate router that received the packet because its address was 
set as de Destination Address) can insert/remove EHs, and they claim 
that that's not a violation of RFC8200.

However, the PSP behavour doesn't even fit in that fictional 
interpretation of RFC8200.

What PSP does is that, given:

  ---- B ----- C


routers, when B realizes, after processing the SRH and setting the Dest 
Addr to the last segment, SegmentsLeft==0, it removes the SRH.

This case is not even covered by their fictional interpretation of RFC8200.

Hence the question is avoided, u<because thye would have no option than 
admiting they are violating RFC8200..unless... who knows... there might 
be yet another curious interpretation of the spec that allows it.


It should eb evident here that the strategy is not really to follow IETF 
process, gain consensus, formally update specs if/where needed, but 
rather push whatever they publish, at whatever cost, ignoring the issues 
raised in this wg, and circumventing IETF process.

The fact that this behavior is allowed seems to be unfair with 
participants, and a dis-service to the group.
