Err. I think we are missing each other's points.

Me:

0) Higlights are reflections.

1) Classic phong is a cheap trick to simulate highlights.

2) Smart phong might be another worthwhile trick to simulate highlights.

3) Rough surfaces blur reflections, but for non-extreme angles the size of
   the reflected object is more significant than the roughness when
   determining the size of reflection.

4) Blurring is important for realism, but good solutions are
   computationally expensive, so supporting cheap tricks is
   important.

You?
