I beg to differ.  This can be a HUGE benifit.

Not so much with actual shapes, as with textures,
and light sources.  Having a "rough draft" declaration
and using it to determine whether you'd like just a flat
gray wall, or a really complicated brick texture complete
with finish, bump maps, and color maps can cut your
render time by more than half.
