I was puzzled by that too. I've used the SQLite amalgamation and thought it was a very clever way of avoiding the complexities of libraries. I took inspiration from it in my chess program and amalgamated all my chess primitives into a single file to avoid the pain of a library dependency. It's an inspired idea and deserves better than "come on".
