It does matter whether it happens at the IP source (origin host, tunnel ingress, etc.) or on the path of that header.
It happens on tunnel ingress and tunnel egress nodes (egress = node
listed in DA of the packet).
That is obviously a lie.
PSP happens en-route. Isn't it obvious from the fact that "PSP" stands
for "PENULTIMATE Segment Pop"? It's done at the last waypoint on the way
to the final destination of the packet.
The same is true for the TI-LFA behavior with you moved out to a
different document: it causes an extension header to be inserted in IPv6
packets while en-route to the final destination
(https://tools.ietf.org/html/draft-ietf-rtgwg-segment-routing-ti-lfa).
It is quite curious the mode in which the proponents of this behavior,
and even more that consensus has been claimed on this document.
I'm glad that there are more eyes now looking at what's going on.
Thanks,
