I'm sorry, I may have been misunderstood. I meant that Dropwizard exemplifies how you can pick and choose components, those atomic libraries, into a "framework" of your choosing. Dropwizard contains very little code. It's just an assembly of the parts you wished existed, and the proof that those parts already exist.
That makes sense, then. Looking at the source code briefly, it looks very similar to what I mean, especially if the parts are able to be used individually.
