I always just presumed there was a contactor in the box because I
thought they could remotely turn off customers for non-payment, or
non-important customers at peak demand.

Perhaps you could cause an overheat by rapidly cycling a relay
controlling an air conditioner. Sounds more like FUD/Fake news to me.
The only thing I've heard of practically is an external connection to
load shed a central air conditioner's contactor for peak shaving,
which just interrupts the 24V control signal from the thermostat's Y
terminal.
I haven't personally seen a service entrance smart meter with a
contactor in it to control a 100A or greater service. I suppose some
elongated beast could exist (no way a big contactor is fitting into a
normal sized housing), but I don't know what the practical purpose of
such a thing would be.
