As 2.4.2.3.1 Solid Mesh points out, the inside_vector is there to allow you
to use CSG with meshes. It also explains to you why POV-Ray needs the
inside-vector for that. If you follow the second paragraph in that section
you can work out why inside() cannot benefit from this: It does not shoot a
ray, all it can do is see if the point is inside or not, and for that
obviously more is needed than knowing which side of the mess is inside and
which one is outside (especially if the mesh is not closed).
