A few times I have seen calipers get sticky after a few pad changes, and
suddenly you have uneven and excessive wear. I have so few brake
problems nowadays that it is not a big issue, but if I were particularly
hard on brake pads, I would service the caliper every 2-3 pad changes.

When I was having "George" do my brakes I was always replacing pands AND
rotors. They used to show me the rotors. Semi-metallic pads? THey would
sure grind them down!

I've never encountered a sticky slider with under 95K miles on it & have not
had to turn a rotor ever, counting from my first car with disk brakes ('77
Chevy). I suppose it can't hurt to do all these services, but my personal
experiences say its not necessary.

Part of a proper brake job is cleaning and re-lubing the sliders and IMO,
servicing the sliders is well worth the 5 minute investment in time.
