Actually, a well-executed clutch kick adds little to no extra wear to the clutch. My explanation may sound condescending but I don't mean it that way. I'm just pointing out stuff using physics-speak.

Clutches burn when they exceed a certain temperature.

Work = energy = heat

We need to dump energy into the clutch in order to heat it.

The engine does no work at all when the clutch is disengaged.

All the work from the engine goes into the transmission when the clutch is fully engaged.

When the clutch is slipping, some of the work from the engine goes to spinning the transmission. The rest of the work goes into heating the clutch.

Work is force applied through a distance, or torque applied through an angle of rotation. We can also think of it as torque through the number of revolutions in which it is applied.

Consider slipping the clutch for a whole second at idle speed. The crankshaft will have made about twelve revolutions in that time.

Now do it for a whole second at 3000 RPM. That's about fifty revolutions; over four times as many revolutions as those at idle.

So, if you slip the clutch for a quarter second at 3000 RPM, it's about as much thermal energy as slipping it at idle for a full second.

To control temperature, limit the time AND torque applied while slipping. If you ever feel it get spongy while slipping it, that's the feel of hot clutch. Avoid that and you're golden
