Where should your subsurface scattering stop if you have only a single 
layer? The clou with subsurface scattering is that there happens something
to your light _below_the_surface_, right? So there has to be a notion of
"inside" and "outside". That's why you need an object with well defined
inside and outside to get this thing working. The "inside" modifies the
light. That's what "media" does. So, using "media" for subsurface scattering
is natural. (However, "media" should be extended to support other scattering
functions.)

A "thin" mesh doesn't make much sense for subsurface scattering. In
particular, if the mesh is infinitely thin. Then you don't have an
"inside" at all!
