What Bruno is describing is the new situation after removal of SRH
insertion at non SR midpoints from NP draft under last call.

Section 8.2 is referring to SRH insertion at the SR encapsulation node (for
example ingress to the domain).

draft-voyer-6man-extension-header-insertion  is progressing as recommended
to relax the RFC8200 restricting EH insertion at any arbitrary node - not
necessarily segment endpoint.

Regards,
R.
