I agree with Zbigniew about this case: The protection fails as soon as
the user opens a terminal window.

Nobody said it was.

And on the other hand: Somebody claiming that something is insecure, and
claiming to have a proof of concept without showing it, is not a proof
that there actually is a security problem.

I asked for a proof of concept only because Tomasz Kłoczko claimed to
have one. I would otherwise be satisfied with a detailed description of
an attack scenario that can be analyzed to see whether it holds water.
I jumped into this debate because I couldn't stomach all the "It's
insecure because handwaving." and "It's insecure because I've said so
several times.".
