Any idea or planned for animation.rigging?

While springbone was a great choice for unitychan, it seem unity officially introduce [animation.rigging package](https://docs.unity3d.com/Packages/com.unity.animation.rigging@1.2/manual/index.html) that seem to have overlapped functionality with springbone

Which I wonder that what would happen to springbone package? Will it be upgraded anymore or have any converter into animation.rigging ?
