It is needed in the case you use other modifiers than subsurf. If you use a wave modifier on a plane, you want may want to unwrap the unmodified plane instead of the waved one.

If the cage is not dense and there is a lot of tris, the distortion due to the second can be very bad, and a lscm mapping for innervertices give perfect results even if the mesh has the most crazy topology you can imagine.

Yes, but if the unwrap is done with subsurf at renderlevel it is not so annoying.
