Can Bone Head/Tail Parent Positioning reflect in export?

With the recent update that allows to position object onto bone's Head/Tail Slider, I notice that it doesn't reflect when exporting in fbx to a game engine like Unity.

Is this intentional? If not, it would be a great support to have. It would help zero-ing out child obj transforms. I've noticed blender likes the center pivot of parented objs in bones to be at the tail end of the bone, while others are at the base head of the bone.
