Yes, this was my sense as well.

When I (wrote and) used these methods, I already had a sense that, for instance, Celeste, Scamper and MailMessage were the "roots" of most of the web classes [at that time].  Nowadays, you would want to include several other root apps, probably, to get the nice results I got.  I believe that Daniel's MudPie would help a lot, both in identifying these natural roots, and in breaking any circularities.
