How do clutches wear? It is not when they are fully engaged, it is not when they are fully disengaged, it is when there is too much power for the clamping friction. Very similar to brake pads which only wear when there is a mismatch between clamping force and rotational power.
With brakes you have to apply brakes and wear them over time. That's what they are made/designed to do. You don't give full force on the brake pedal on every stop, if you do you're doing it wrong.
A properly driven clutch will still wear over time. But, most of it's wear occurs during take off where you have to modulate the slip, and during hard, high hp shifts where the clutch still slips a bit between shifts, as it gets bite and grabs.

The DCT does this too. It has to so that it can accommodate a driver who takes off slowly form a stop vs a driver who wants to launch it at every start.

I'm not talking about poor clutch control where one rides the clutch while moving or shifting through every gear.
