I think perhaps the cleans should be removed or perhaps replaced with curls or something,because of their intense technicality.
The benefit from doing cleans far outweighs the benefit from curls. The 5 exercises are the 5 basic exercises in Rippetoe's book. That's why they are what they are.
Cleans are not that complicated. Most people can teach themselves how to do a passible clean in relative short order using Rippetoe's books and online resourses. That won't get you to the Olympics but it will get you stronger.

Tables for the basic barbell exercises were developed from:
definitions in "Practical Programming" by Kilgore, Rippetoe, and Pendlay
the experience and judgment of the authors,
the exercise techniques described and illustrated in “Starting Strength” by Rippetoe and Kilgore, and
published performance standards for the sports of powerlifting and weightlifting.

Kilgore, Rippetoe, and Pendlay collectively have a lot of experience. I wouldn't argue against any of them.
