If it shut down for a few seconds, would not it use more energy
switching back on again than it saved by switching off?

I think that is entirely possible if you take your current refrigerator
and add a simplistic device that switches off at least the motor for a
few seconds. But if the device has been designed to support brief
interruptions, then it could be designed to behave more intelligently.
Maybe to wait until the motor switched off anyway before applying the
interruption. Sure, that reduces the speed at which load is shed, but
maybe that is not so very important?

It makes little sense to switch it off for seconds when a filled freezer can be left off for an hour without issue. Just shift the temp setting by 1C.
