I think disc brakes on road bikes are inevitable, but not out of need, more for money spinning purposes.
On mountain bikes they undoubtedly improved things, but improved braking on a road bike is not strictly speaking a necessity like it was in offroad cycling - of course improved braking in the wet comes with discs, but you can also say that if you're surprised that your dual-pivots brakes don't work especially well in the wet you need you to work on your 'road-sense' a bit.
As for the OP, putting a front disc on a pista would firstly be a hassle (new fork and hub), and secondly be total overkill, and possibly a bit daft.
