Dibbs,
I find the tarogato report interesting, indeed. A testament to the notion that different cultures make more of an effort at hand bias accommodation. Certainly no accommodation was given in the US when I was a youngster. I suspect most of these things get settled by tradition and expectation.
Of the aforementioned, if anything, perhaps they ought to call it the Right Handed clarinet. As a south paw myself, I always put the left hand above the right.
I see no advantage, but will commend the creator on the painstaking task of mirrored recreation!
