Yes, the Classic rules provide for "Fidelity" points - though few contests actually employ them (including the VSC). Fact is, they're just too difficult to assign, given the few remaining folks from "back when" who knew the original designs and thus know the difference between those and "faux" versions.
IMHO, the biggest affront to Old Time & Classic has been the acceptance of electric power in those events. (This, by the way, is an opinion shared by the leading proponent of electric CLPA...and y'all know who THAT is.)
