For people who read SO (rather than ask and answer), SO is useful in the places where the documentation is lacking.
The way to integration that content into an existing project would be to document it better - possibly with a FAQ for development questions. That doesn't really need CC licensing (its helpful, but not essential) in that people who want to contribute documentation can already do so.
Just pull up a SO tag for the library, find the top voted question, and figure out where it goes in the docs.
Q&A shouldn't be used as an alternative to documentation.
