Interesting: It appears that achieving high edge angles is a goal unto itself, rather than a component to achieve a short-radius turn. (Short relative to the speed).
Achieving the edge angle seems to be a fashion statement (it looks cool), instead of a necessary element of a high-G turn.
Angs look cool and feel cool, what other reason is there to do anything on skis? And yes, good skiing is kind of fashionable on insta/youtube, but the vast majority of the skiing public don't care at all, and like skidding around on fat skis whilst standing up straight.
