Oh I do.

And I want to sincerely congratulate three of you to be very effective to
discourage touching IPv6, its dogmas and principles. If this is good for
the industry, time will tell.

To me I got even more assurance now that IPv6 with its 40 octet fixed
header is a broken concept and deserves to be obsolete very soon -
especially for intra-domain use cases.

Btw new data plane much more efficient can be easily made compatible with
all existing and deployed v6 capable data plane hardware. If I would work
for a vendor perhaps I would have some cycles to propose it, but otherwise
it is just impossible to get sufficient support and get through with new

Kind regards,

PS. @Fernando ... you keep forgetting in your post and your errata about
RFC2473. I recommend you take a new read of it including section 3.1 and
match it against your IPv6 end to end principle. It is roto operational
principle behind SRv6.
