A stem's handlebar clamp doesn't know what handlebar you're using. A FD clamp doesn't know what your seat tube can withstand, etc. The advice to use the least amount of torque necessary to hold is the best advice.
Obviously (hopefully) CF paste shouldn't be used on threads/bolts - eg. the OP's headset -- I can't imagine there's anywhere that you'd use CF paste in that scenario.
