Point query feature(find nearest hit surface point for a given point) is useful for physics(collision detection), distance fields(e.g. monte carlo geometry processing) and so on.
Here is an example from Embree.

Changes required should be rather small since we already have BVH traversal and ray/prim intersection logics.
