This too is a *fundamental* difference between QKD and classical

What does this "classical" word mean? Is it the Quantum way to say
"real"? I know we're in violent agreement, but why are we letting
them play language games?
IMO, QKD's ability to discover passive eavesdroppers is not even
interesting (except from an intellectual p.o.v.) given: its
inability to
detect MITMs, its inability to operate end-to-end across across middle
boxes, while classical crypto provides protection against
eavesdroppers
*and* MITMs both *and* supports end-to-end operation across middle
boxes.
Moreover, the quantum way of discovering passive eavesdroppers is
really just a really delicious sugar coating on the classical term
"denial of service." I'm not being DoSed, I'm detecting a passive
eavesdropper!
