Ian, as you correctly say, both rear wheels turn at exactly the same rate as one another, but the outside one takes a longer path round any corner than the inside one. The fact they are both at the same tangent to the corner radius doesn't change the fact that they are traveling at different speed relative to the road surface, yet are forced by a fixed axle to carry the same angular velocity as one another. So there HAS to be tyre scrub, whether the front wheels are pointing dead ahead, or in positive or opposite lock.

This idea that the action of a diff is reversed by understeer or oversteer is complete nonsense. Just draw the relative path of both rear wheels round a corner. The outside rear wheel ALWAYS travels further than the inside rear, and so is ALWAYS the wheel that carries the higher road speed. Your explanation, much lauded as sound theory by some here, doesn't even stand up to the most basic scrutiny. The rear wheels ONLY want to travel at the same speed when the kart is traveling in a straight line.

I agree that there is no such thing as too much grip, it's more a question of setting the kart up to exploit the extra grip when it becomes available. Taking measures to lose some of it is the wrong "fix" for that problem. However you contention of "no drag" when the steering is straight ahead doesn't work with the physics. That's why I think a tiny bit of positive lock can help by unweighting the inside rear.
