Good question.
By having more brake area...two rotors and the pads contacting it...you'll have more brake power, with everything being equal.
Now, sometimes a master cylinder from a single brake set up is not enough to give the proper leverage for power and feel.
Is it necessary?
I really don't think so. If you had a GSXR1000 going warp speed, well, yeah, the extra power would be great, and probably necessary at that speed. For a built Hawk on the race track? Probably more to be gained by not having so much extra mass (rotor rotating...and the caliper hanging on the fork) on the part of the bike that has to actively react to bumps.
