Did you take the switch plate off and see that no wires were connected
to the switch or did you assume since you don't see it operating
anything it is not connected?

You probably know this but FWIW some wall switches switch only 1/2 (i.e.
top or bottom part of wall plug). You should test the plugs one at a
time with wall switch in both positions to verify that nothing becomes
hot. Use a lamp or test light. It is highly unusual that an
electrician would use up a perfectly good switch rather than a dummy
plate plug. And installing dead switches is probably a code violation.

One exception I can think of is in a room with a ceiling fan. There
could be a separate switch for the fan and a switch for the fan light
kit. If the fan doesn't have a light kit installed the wall light
switch for the fan light will not operate anything. That wire however is
deadheaded at the fan not at the switch.

Most every time a switch will be wired and is "switching" something.
