I disagree. A telemark turn applies less force to a ski than the equivalent apline turn. Look at the big heavy bindings on racing skis, and the fact that they don't race with a telemark turn. Much higher forces at work with an alpine turn.
I only think you need inserts for increased shear capacity if you are a big guy, and routinely ski at super high speeds downhill. For most cases, the only good reason for inserts is the binding interchangability (if you want that), IMHO.
