So the most basic use case I needed it for are the wind affected objects:
Moreover, the speed of a hero in an RPG game could be leveled up, so it’s nice to also increase the framerate of the running animation in parallel with increased movement speed.
Next, I could now check what frame of the animation attack is actually playing and apply some effect then, for example in the frame when the sword hits the mob the mob should play a hurt animation and the damage should be calculated and displayed above the mob, and even some particlefx could be played in that particular moment!
We are going in the direction where we could animate almost anything and it gives developers infinite possibilities! 
It’s great! 
Thank you very much!
