Even doing SRv6 does not need to imply doing EH insertion.

For instance, I just re-read
draft-voyer-6man-extension-header-insertion, and there's no comment
whatsoever why they don't address the same issues with encapsulation.

The ietf consensus on this topic resulted from technical merit.

I don't think it's productive or even fair to simply ignore such
discussions and consensus, and ignore standards at will.

If you don't like the standard, make your case why you think it should
be updated, and work on it. The onus is on you to change the standard,
not on the standard to remain "as is".

Is IPv6 an end-to-end protocol if you allow EH-insertion in the middle
of a network?
