The dangling I am talking about is a result of the harness, climbing or otherwise. It is being connected to the end of a long string that looks kinda silly. Action sports go through a refinement process where participants first concentrate on learning basic trick, then explore the range of possible tricks, then expand the scale of tricks, and finally do everything big and with style. Style usually is comprised of smooth, fluid, controlled motion. Dangling while gliding seems to be currently in direct contrast to style even when done by really good kiters.
I guess it depends on your definition of style. Most handlepasses lack style IMHO. Some of the simpler tricks look better because they can be done with finesse and grace. I agree that gliding does not always look graceful, it depends on the rider just as any jump. However, I can tell you that gliding feels graceful. Instead of a boost, you just sheet-in the bar, lift your legs and float upward on the updraft. The perspective in the air is amazing as well. You get a birds-eye vantage of the entire area.
It may be a flash in the pan for some people, but for me gliding has added more to my stoke for the sport than any other single aspect.
