I also support Suresh's proposal.

IMHO this plan explains exactly why we rather need to make it more
explicit in rfc2460bis that this version of spec does not assume EH to
be inserted or deleted except at the source node (not "domain").  I'm
totally open to the discussion of possible extensions with the concept
of "source domain".  But it should be fair to say it will take time,
at least for months, and quite likely more than a year.  If we keep
the rfc2460bis text "ambiguous" in the meantime, we'll leave the risk
that it's interpreted more loosely and someone develops an
implementation that violates the assumption more casually.  To me,
it's more responsible to be more explicit in the current specification
to prevent further accidental misunderstanding unless and until we
have the possible revised conditions.
