We showed that the investment in time is rather small and the benefits are automatic lists and the ability to support modular documentation using transclusion.

The investment in time to learn projectdoc, especially the macros involved to render automatic lists and use transclusion, is probably much larger. Fortunately this is also a one-time investment.

What you gain:

1. Automatic lists of matching documents
2. Support for modular documentation based on transclusion

We think the reward is larger than the investment. Do you agree?
