It's something I did in elementary school, with no intention to ever train bar beats, before having any real skills. Doesn't require having a vertical cast or giant to perform.
Let's look at a recent competition:
Most of these gymnasts could improve their score if they did the B hecht dismount. One of them fell on a Double Tuck, and injured themselves. That's the inherent risk in trying to learn and perform a double salto skill. It takes less time to learn a hip pop, less physical exertion to execute, and is less dangerous. It's stubbornness or ignorance if coaches don't want to consider teaching a safer dismount that is less deductible. Give people options so they can figure out what fits best.
