Asymmetrical skis are not a new thing. Beside those mentioned I know such skis made by a tiny private manufacture in this country in the early 70s.
In the pre-shaped era the last ski of the sort was Volkl P9RSL in about 1995 which should have been a "two in one": both a SL with shorter radius and a GS with bigger. (Watch out: it was not the famous race ski P9!)
The first retail Atomic Beta Race 9.28 had radius 28/30m but the next 10.26 not anymore, I´m sure (similarly, afaik, the racestock 9.28 with full-length Beta lobes was symmetrical).
The radically shaped "extreme carver" Beta Carv 9.11, later 10.11, also had 10/11m till 2001/2002.
Fischer was another one with its first Radarc (you might remember the crazy shape which couldn´t stand on tails) built according to plans and theories of an Austrian Helmut Gottschlich (the father of the Wiener Modelle aka PSIman) and the first and second? generation Radarcs were asymmetrical too.
IMO the benefits - if any - haven´t outweighted the disadvantages. It´s a complication (I suppose it´s simpler to cut materials symmetrically), you can use the moulds for asymmetrical skis only, there would be problems programming tuning machines.
From the skier´s POV: the idea is not illogical but I think that in practice the skier seldom pressures both skis long enough for the different radii to really apply (I´m speculating here, not sure).
As a customer/user I would never buy such skis simply because they would last half the time. Considering how fast a season on hardpack/manmade snow eats up the edges they would be one-season skis for hard chargers. The L/R switch is important.
