Change/update animations

I'll be quick: 1.- The witch, she was added 11 years ago and I find it absurd that she still doesn't have a potion throwing animation. She throws potions from her chest. They could add that she at least separates her arms and then throws bottles with potions. She would make more sense. 2.- Each mob (including the player) should have its own movement and action animation. They should apply more fluidity and importance to these points. 3.- There are mods and texture packs that already do this type of thing, but why not revolutionize mob movements with a new update? I feel like this kind of suggestion would give the game more life. I'm going to clarify that I'm not demanding a more realistic game, but rather, MORE ALIVE. I have been playing Minecraft since my childhood to date and I would like the developers to make a new animation system or at least consider one of the 3 points I left above. A cordial greeting to whoever reads or answers this. (':
