Is there plans for more animation updates?

Less than a year ago (I think), Jax got his auto attack animations updated as they were very clunky, resulting in a much clearer and more fluid animation. Then few month ago Xin got a gameplay update, along with a small animation update (notably on spells and auto-attacks, but also on his idle and walk animation.

Is there going to be out-of VU/GU/VGU updates for animations on older champions? I feel like a lot of them would need it, not only for gameplay/clarity purpose but also thematically.

Let's take Katarina as an example. She is supposed to be a swift assassin, blinking rapidly to execute his target(s). Her idle animation/pose doesn't show that. She looks blocked, and have more of a on-the-defence stance rather than a ready-to-kill one. Ideally she should have stance similar to the one in the assassin update's login screen: https://youtu.be/78YQGeYE2Uo Same goes for her auto attack animations, while good and mostly fluid, they are still on a defensive stance.

This aside, there are champions left with no fluid transition animation from the end of auto-attack to the start of idle (as an example), leaving a very robotic result.

Is there any plans for animation updates?
