Is Spine not more need it?

As Unity has its new animation system, with form deformation, is Spine obsolete (at least for people who stick with Unity)?
If the answer is yes, there's a way to get Spine animations in Unity native system? Not importing the json and atlas with the Spine Importer, as we now do, but a native animation system that can be changed via Unity Editor?

 

I Google the same thing, more than a year later, and I came to this!
