I had thought that part of the meeting would be to address the tension
between these two issues, but I have also since learned it has become
"how do we evolve the Internet to accept whatever middleboxes want to
do" - i.e., precisely the latter of your examples.

Not according to the current Internet architecture, but that's back to
my point above.
An architecture is defined as much by what it is not as what it is. If
everything is on the table as changeable, then there is NO architecture
anymore.
If you believe in 'permissionless innovation' then everything is always
on the table.
That's called "anarchy", and the results only serve to increase entropy.
The Internet architecture to date has been what survived a
Darwinian process.
First, it's not Darwinian so much as mutation caused by high-energy
radiation, and no, it's not clear to me that "architecture" is
surviving. Sometimes the result is just glowing goo.
I don't believe in in ancestor worship.
Nor do I; I do believe in deliberate, thoughtful changes to
architecture. That's not the same as the anarchist view, or post-facto
"let's figure out how to change the architecture to accommodate the
anarchy".
In good design, sometimes the answer has to be "NO". If that's not the
case, then you have no architecture.
