Of course some people who are used to MitMing connections will
have problems and will have to change.

But that does not mean that their problems ought to be solved
by any change to TLS.

IMO the costs to the broader Internet of breaking TLS like that
are far too high to optimse for these folks. It's understandable
that they'd prefer otherwise.

People with such problems should IMO look elsewhere for
solutions and not be fixated on breaking TLS.

Lastly, bear in mind that even if the people with whom you
are dealing have the best intentions, there really are people
who are paid large amounts of money to weaken Internet security
(see [1] for scant detail of just one country's efforts in
that regard) and that we have IETF consensus to oppose such
efforts, as far as it's in the IETF's remit to do so.

So it doesn't really help the discussion to claim that
such-and-such a (set of person(s) is/are good actors - we do
assume that, but also that there are others who would like
the same changes to happen who do not share the IETF's goals
of making Internet security better as far as we can.
