It maybe doesn't fit the metaphor quite as well, but as an operations person, I've frequently run into the "underfitting" problem. For example, we run Chef to manage our physical and virtual infrastructure. There are a ton of community-authored Chef cookbooks available. Which at first blush, sounds great. But often, they have grown over time to become these awful hydras that try to be all things to all people. PR after PR has added support for the specific use case of every organization that wants to run the cookbook in their own special way. The "Getting Started" section of the README eventually becomes a dumping ground of 900 attributes you need to set correctly, and yet somehow it still doesn't quite perform how you'd like.
In many cases, we've tried to use community cookbooks and even merge our own customizations back upstream. Only to eventually give up and write our own version that's 50 lines of Chef DSL/Ruby instead of 5,000 but does exactly what we need, the way we need, and no more. It's very possible to make a system too generic and configurable, to the point where it loses all meaning.
