It's the minimum spec target profile for Nvidia's Cg compiler.

ARB_fragment_program_shadow may leave it undefined, but the GL spec says the
texture unit operates in the normal manner and texture comparison is bypassed
if the currently bound texture's base internal format is not DEPTH_COMPONENT or
DEPTH_STENCIL.
