They did get excited? Khorkina and Chow - for whom the Stalder 1.5 was named for at the time - received praise throughout the 1994-2000 period for their use of stalders and pirouettes at a time when a Giant 1/1 was a D element, and close-bar skills were seldom seen.
Since when do gymnastics fans not get excited over new skills, period? Excluding Amy Chow’s failed attempt at the 2000 U.S. Classic, the Weiler kip itself is only ~15 years old in WAG. Since 2009 and more-so 2013, the event has moved further and further away from pirouettes and non-flight elements in forward grip, which this skill has both of. Nearly all innovation on the event in recent years has been in the form of Tkatchev-type elements in different body shapes and with/without “1/2 turns.”
Fans were similarly excited over Semenova’s “1/2 turn” added onto an in-bar 1/1 back in 2009, and I’d love to see skills like an endo 1.5, forward sole-circle 1.5, jam / “Luo” with 1/2 turn, etc.
Had she competed it during the 2017 - 2021 COP, she’d have earned the same CV for the Weiler 1/1 + Piked Jaeger as the Pak + Shap 1/2 connections that had become almost compulsory.
