Sure.

This was your question:
<https://www.ietf.org/mail-archive/web/v6ops/current/msg21680.html>

This was e.g. Joel's response:
<https://www.ietf.org/mail-archive/web/v6ops/current/msg21685.html>

Section 4 (and subsections) of our document is all about that.

Every time the issue of EH packet drops comes up, discussion eventually
becomes about "but hey, why are you looking deep into the packet?". --
And a large part of our I-D talks exactly about that.

Thanks,
