This was disabled to avoid updating the geometry every time when the material includes displacement, because there was no way to distinguish between surface shader and displacement updates. As a solution, we now compute an MD5 hash of the nodes linked to the displacement socket, and only update the mesh if that changes. Differential Revision: https://developer.blender.org/D3018
