OTOH, if they were to raise their thermostat's setpoint
that degree (or two?) all the time, they would probably not
notice the difference.

But, as I've commented elsewhere, as soon as the AC is powered up it
will stay on for longer to bring the temperature down again.

There is an energy saving,

Radio-controlled AC turn-offs are not meant to be energy saving.
They're meant to be peak-load lessening. It's meant to prevent
brown-outs because of too much load at one time.

but it's very much a second order effect,
arising form the slightly higher average temperature.
