Writing this without any hat,
Please note that on the logical side, it still have to be "proven" that this idea is strictly forbidden by RFC 8200.
Here's the proof part:
1) Isn't IPv6 end to end?
2) How do core components of IPv6, such as AH and PMTUD work in the
present of intermediate nodes that can add and/or remove arbitrary
extension headers?
It should be clear from the above that EH insertion/deletion is forbidden.
Since this topic has been brought up again and again, I have submitted
an errata to RFC8200 which clarifies the intended behaviour:
* https://www.rfc-editor.org/errata/eid5933
(that's what Errata's are for, after all... and it should be clear that
the EH processing part, overall, needs improvements).
Thanks!
Cheers,
