There's no reason to rush this transition with an 11 year old. This is a key skill and with the focus on handstands, it is difficult to do correctly. I am sure she could probably "throw it" if her coach let her roll over and do it way past handstand, but why do that with a young optional who will presumably continue to progress and eventually need this skill as an entry into front giants, jaegers, or straddle backs? These skills are not used in level 8 as a general rule (they can't be anymore, but when they were allowable it was very rare) and aren't even necessary for level 9, although they're nice, and open up routine options. But when your daughter does level 9, you will see many routines that look like: jump to high bar, cast, shootover, toe on shoot to high bar, free hip/two giants to double back. Or pak salto, half pirouette, or half pirouette on low bar then straddle back, to two giants dismount. Clean routines like this, that hit all the handstands (on the shoot 1/2 and straddle backs too) with good amplitude tend to score pretty well, and many first year level 9s are not yet consistent enough to combine the harder combinations with the releases and two bar change routine. You will see that many girls do two or even three years at level 9, so the routines will upgrade over that time.
Basically, for a JO path and at this level, I don't find it strange the coach is taking about a year to develop this skill. Many higher level optional skills are introduced way before they're mastered. It sounds like it's not a critical skill yet for your daughter's routine progression. Progress in gymnastics tends to slow way down at this level for gymnasts who previously mastered everything in a few months or less. The skills and combinations take more refinement to do independently.
