Cutting is acceptable since removing coils DOES increase the spring rate. The main problem with cutting is that most people cut too much, and it reduces the free height of the spring which can lead to the spring falling out of the mount when the suspension is at full droop. Heating springs does the same thing, too, in addition to fatiguing the metal and giving you a low, soft spring.
You'll notice that aftermarket springs all use 'dead' coils at one end to keep the spring's free height close to stock, but let the car sit lower when the springs are installed.
