Does anyone know the reasoning for making 1/0 the smallest size for a parallel conductor?

To keep people from using parallel when a larger wire size would serve just as well?

I have no fact to offer, but here is my guess. No two wires will have exactly the same resistance, however carefully you cut them. Small differences in length or other parameter can cause one of the two wires to carry more current than the other. The smaller the wire you start with, the greater impact that that difference in current can have on the more heavily loaded wire. For larger wires, a difference of a few amps will not be as much of a hazard.
