I think it's important to recognise that there are many different ways to get up a piece of rock, these are a choice in "style", and each style has different challenges, different qualities etc. No one style is better than another, they are a personal choice, and this is part of what makes the sport so great... if you want to invent a new style, you can, it can be completely made up and personalized and obscure, perhaps it is even a one time thing, climb route x in slippers on christmas. People only argue about the validity of the most common styles, but they often forget they are only a style.
