Bone Animation Tag?

Would it be practical to have a tag for animations that obviously have a bone structure for assisting their animation?
Example: post #4035806
Non Example: post #2494845

There's a tag for that specific kind of animation in your example, it's called live2d, though it's often missed.

You learn something new everyday.
I genuinely have never seen the tag. Only 153 instances...
I've got some tagging to do!
