Yep EstCstSkr - the very definition of dynamic precludes the possiblity of there ever being just one right way.
And in fact, the Austrians are not always using equal weighting in all conditions and turns. It is quite predominate in SL, however in GS I've got tons of recent footage showing the complete opposite. There is no ONE right way ski, great skiers can ski on just the outside ski, both skis, or even just the inside ski.
As to getting more 'energy' somehow: Modern stiff racing skis are beefy enough that most of us already cannot bend just one of them to their maximum potential (which is how you store energy in a ski) and when bending both we only bend each 1/2 as much, resulting in the same energy storage/release and a larger potential carve/arc radius -- which is some situations is great, just not ALL situations. Hence another reason we want to adapt constantly.
Using two skis does give you more edge interaction with the snow, and more stability and possibly steering accuracy. So it does have benefits.
Again, I'm not saying that more equalized weighting isn't great . . . it is. We've been doing it for decades in some situations, and the new technology is making it even more useful. Its just not THE ONLY 'correct' way to ski.
A good reason the Austrians are always on top of the leader board is not any one specific tool in their large bag of tricks as skiers. No, its that their entire bag of tricks is much deeper, more disciplined and intuitively implimented. This is because skiing is their national sport. Their best atheletes, top trainers, most money, national attention and educational focus goes into skiing . . . not basketball and football.
I went to High School in Germany, I raced and so was training and being coached on the snow 4 1/2 days and 3 full days a week. Our head coach was Austrian, its a different ball of wax all together - and its not because of any trick tecniques they use more than us. Its about the fact that they have the top atheletes in their country in the sport, and their approach is extraordinarily disciplined (and in fact ruthless).
