Why not?  I think having the option to apply a displacement instead of
a normal to any object would be useful.  Applying a normal does not
affect the shape or the shadow of the object.  Applying a displacement
should.  I realize that an isosurface can be used in many instance to
obtain the desired effect, but I also think it would be useful to be
able to build more complex objects with primitives, then apply a
displacement as you would a normal.

I think having the option to support a low-poly mesh, which can then
have a displacement map applied would be a nice feature.  I agree that
you can have any level of detail in a mesh, but the size of the mesh
grows exponentially as the level of detail increases.  Additionally,
it would be nice to have the ability to apply a procedural
displacement in this instance.

Again, thanks for your feedback.
