The point of the shottkey clamp is to prevent the transistor from going into
saturation.  As you pointed out, you want the transistor to spend as much
time as possible fully on or off in class C operation.  If you had a
shottkey clamp, it might be able to switch off faster at the cost of more
dissipation in the on state.
