Found this video of Alex Kunchevsky animating a butterfly in Dreams. If this is how the process actually works, then I could see Dreams being very popular. Simple and intuitive.

Of course, I could also see edge cases where the simple & intuitive get in the way of what the artist actually wants to do. Will be interesting to see how it pans out in practice.
