Partial Support, seeing as that there are people out there that will create the most ugly, eyesore animations. There's the possibility of epilepsy, though that's an extreme. And I'm still not convinced with the storage size problems, and the fact that someone might have a skin that you can't stand the animation of, but there'll be other people with amazing ones at the same time. And it's not like Mojang will go and make a player skin blacklisting function anytime soon. That's why I've only given partial support.
Other than that, I'm personally rather excited with this idea. Good luck to it. :3
