It may just be that LW just calculates the vertex normals from the face 
normals...to do otherwise would seem to be a lot of work for little or 
no reward.

Vertex normals aren't perfect in all situations either. Consider a cone 
formed of a fan of triangles. Each triangle has only one vertex at the 
point of the cone. You will have as many normals as triangles at that 
point, and no interpolation between them...
