Of course yes.

It seems there's some level of recurrency in this area. Folks trying to
do an under-the-cover update of RFC8200 (wrt header insertion), or
simply ignoring what RFC8200 says.

We have been a long way in this area (to an extent of having to send
back to the wg what would become RFC8200 (then rfc2460bis) because folks
from one specific vendor were trying to push that agenda.

It would seem to me that having us wg participants remind folks that you
can't just violate specs (RFC8200, and Internet Standard) at will, or
keep an eye on every move that is taken in this respect (e.g.
<https://mailarchive.ietf.org/arch/msg/ipv6/12Qwp_eeQT2EmbUrSxBLL5HTcnM>) does
not seem to be the best way to spend our time, and also becomes
uncomfortable.

It also seems to me that the work of spring and 6man should be better
coordinated. At times it would seem to me like things are cooked up in
spring, and then 6man is expected to adapt to that. -- when, if you want
to change a standard, the place to do it is 6man, and not elsewhere.

So, to make the point clear, until there is a point where there is wg
consensus in 6man to formally update RFC8200, an Internet Standard, can
we please remove from all wg documents any sort of EH
insertion/removal/mangling?

In that light, may I ask the ADs that these things are better taken care
of? And that given the controversy around the topic, any decision taken
in this respect is CC'ed to 6man, and a decision is taken *on the
maIling list* (as it should)?

Thanks,
