I think people might be assuming that ambiguity is the only cause of people
thinking EH insertion is permitted.

I think there are at least four potential other reasons:

- they've never read the EH section of RFC2460, which is clear about what
and where EHs are allowed and intended to be examined and processed.
(Specifically the second and third paragraphs, after the diagram.)

- they've read the EH section of RFC2460, understood it,  but they've since
forgotten what it said.

- they've read the EH section of RFC2460, understood it, but have chosen it
ignore it.

- they've read the EH section of RFC2460, however haven't fully understood
it properly because English is not their first language.

I would think in this last case it is likely that at least the term
"processed" would be understood, because a version of that word is part of
the acronym CPU.

I'd really like to see it explained how those EH sections if RFC2460 are
ambiguous before I'd be willing to accept that claim.
