Future at the level of annimations?

Hello, I'm Dreyka Oas (formerly called MC Oas), since 2013 I'm on MCreator, at the beginning we could make only simple mods but today it has become almost a norm for me. But there is still a long way to go and that's why I'm asking a question that I'm looking forward to, when will the animations for the entities be more customizable. I ask this question because for me it's still very aproximate as a way to give animations.
