I think the catch is the the majority of programs are more linear than the index of methods would give credit to. Sure, some folks are making utility data structures that don't really have much of a narrative to them, I suppose.

I would think for most programs there is a very direct sense of linearity in getting a task done. Sure, you will often have a lot of support methods. But seeing them just directly listed can be as much of a distraction as anything else.

Note, also, for nontrivial applications, you will likely have a collection of literate programs. Not just one giant literate program.
