I wouldn't mind seeing fewer "nutcrackers" and "swan lakes" and such in figure skating and see more interesting programs that are truly original. Heck, as you note, even ballet has gone far beyond those staples and now ballet dancers will move to almost any kind of music and do all kinds of things on pointe. Sure - they perform the classics - just like orchestra's will never stop performing Beethoven's 9th - but ballet companies have never stopped exploring.
I don't hope that fewer skaters will pay attention to line and turnout. Sorry, but for me it completes the picture. I'm absolutely mesmerized by Kim Yuna. On the other hand, she would just that much more exquisite if she turned out her leg and pointed her feet.
And I don't necessarily think skaters should be pretzles. Michelle Kwan looked exquisite to me. She was no pretzel. But actually, she did pay attention to line and to pointed feet. And it helped paint the picture she did. For that matter, although flexibility is obviously extremely important in ballet, it's more about forming the correct line - The relationship between your back and legs in an arabesque for instance.
I do realize that pointing your feet can't possibly be the most important thing in skating and I can understand that it's far more valuable to concentrate on edge working and jump technique. But let's face it - skating is not at all the same thing it was in the age of Henie. It is very much about dancing on ice and music, so skaters might as well look good while they're dancing.
And stretch, lines and attention to feet, back position, and turnout - whether you are intending to flex or point your feet or turn in or out is important in all kinds of dance, incuding modern and jazz.
Just my own personal bias that I can't get rid of.
I agree with Ivy that it would only impoverish skating to ignore the bueaty of dance that inspired such things as the layback in skating.
