I don't think as part of a standard process it would make sense but sometimes the mind wanders when the minutes drag. if one found they had 1mm of twist in the front, at the end of their HT alignment bar, they could in theory pull that out by boring based on perpendicularity to rear axle. I haven't done the trig to see how much one could remove within the 0.5mm of material that has to be removed anyway but it seems like 1mm could be covered.
