Absolutely in the learning stages of forward twisting.

… putting it on Floor I only do pike open twist drills with kids that are twisting too early, though.

Then I teach them pike full, pike 3/2, etc, without ever actually telling them to open it up to the layout. The result is that the pike gradually evolves into a hollow, and the open to twist comes earlier and earlier, but they always retain that split second delay before twisting.

So the idea is similar, I just teach it as a pike rather than a hollow.

In a perfect world, with great kids, this is a super technicque.

In the real world, with real kids, the problem long term with that skill is that kids twist TOO EARLY. All my drills emphasize getting into the arched position as quickly as possible. Twisting as late as possible.

I find that if I do my drills, the skill will eventually end up as discussed in the drill. It's easy to get kids to twist earlier. It's easy to get them to take off in a more hollow position, … if you train a lot of arched layouts first.

There are many roads to arrive at the same place.
