Hi Joe,

I'm sorry, but I gotta say that answer seems to me both unresponsive
to the questions asked and unconvincing.

Without rough consensus to adopt, the work is not adopted.

But your statement above isn't accurate - it wasn't "this work"
(as in this draft) that was discussed in Prague, but rather the
entire idea of weakening TLS in these ways - quoting from the
Prague minutes [1]:

"The main question: Is this subject something that the WG should
consider?"

There is clearly no consensus to adopt *any* work in this space,
whether that be draft-green or this latest iteration from Russ
and Ralph.

I see nothing whatsoever to indicate any significant change in
sets of opinions since Prague.

What makes you think iterating on yet more proposals like this
will ever conclude? If there's no evidence of that we ought not
waste the time and energy. Can you point at any change that
could possibly indicate that this bun-fight is worth doing yet
again?

What significant change has there been since -00 of Russ and Ralph's
draft? I see nothing major there. that -00 was debated on the list
which is the primary place for  discussion. My read of that set of
threads it that it pretty clearly showed that the same folks have
the same opinions with no significant movement. Can you point at
some evidence to the contrary? If not, we shouldn't bother to waste
more time on this.

If instead you mean Russ and Ralph's draft differs from draft-green,
then see above - it wasn't only draft-green that was rejected in
Prague, but the entire idea of adopting work in this space, which
includes Russ and Ralph's -00 and -01.

That the authors have asked for time counts for nothing, when the
WG have no consensus to work in this space. If just asking for time
does matter, then I'll now publicly repeat my request for time
to refure the assertions that'll be made for breaking TLS. You said
no to my request, so what's different about one that relates to a
draft that has been debated on the list and attracted significant
negative comment?

It is not "some repetition" - this topic has been debated f2f and
on this draft on the list and there's zero evidence of significant
changes in opinion, in fact the opposite. Can you point at any
such evidence? If not, your position as chairs seems illogical.

But the WG has already demonstrated a lack of consensus to even
consider "work in this space" (your choice of words I believe.)
That should be enough. What does or doesn't happen outside the
TLS WG is not at issue here.

To reiterate, in Prague you asked "The main question: Is this subject
something that the WG should consider?" The result was a clear lack of
any consensus to work in this space, which means not working in this
space. Yet here we are again giving agenda time to highly controversial
proposals in this space.

Please: just take this off the agenda and let the WG do it's real work.

Thanks,
S.
