The crushed walnut doesn't get stuck in the primer hole nearly as bad and works quicker (less tumble time).

? Depriming brass doesn't clean the flash hole. That's why there are separate tools for that. Progressive press or not, doesn't matter.
The reason most reloaders tumble/clean brass before depriming is to prevent excessive wear on the inside of the sizing die. Though that can be avoided by decapping in a separate operation.
