The first two are referenced in the game and do not appear to do anything when playgroup forward is applied.
The last one was not used by Bethesda, but curiously enough works fine.
Makes me think Beth disabled the animation in the first two NIFs, but I don't know enough about Nif transforms to figure out what they did or how to make them functional again.
