My money is on an epic troll. Four out of five network engineers surveyed
agree their individual IP headers are best served without condiments.

Your man; he is made of straw. :-)

Speculative is orthogonal to small or incremental; they are different
This is also true of the difference between addresses and names. Addresses
are an engineering artifact; names are a business/administrative artifact.
*The entire point* of DNS vs IP is to uncouple those; necessary changes in
the engineering artifact *MUST not* cause changes in the business artifact.

And, unsurprisingly, no one made an argument that trivial. To the extent
you think we did, I think we were merely giving you the benefit of the doubt
of already understanding this dichotomy, which is pretty much Networking
201, and taken as read on NANOG.
Extraordinary changes require extraordinary justification.

I didn't see anyone make that implication. Could you quote?

Yeah; that approach didn't work out well for Jim Fleming. :-)
Seriously, Barry; my appraisal of this after three decades is that this is
first year stuff, and you are not a first year guy, by any stretch.
So, is this just the epic troll of the year? Or is there something we're
