How to use the Displacement output of MatLayerBlend_StandardWithDisplacement?

Hello, I was really excited when I found out there would be a material layer blend capable of blending displacement values, but when I finally got around to installing 1.8.0 today and placed the MatLayerBlend_StandardWithDisplacement node, I saw there was a Blended Material output, which obviously goes into the material attributes, but there’s also a separate Displacement output on the node as well, and I can’t seem to figure out where that would go, since all the previous layer blend nodes only had a single output.

So where or what would I plug the Displacement output into?
