It's NOT a hack because the bindings are calling directly into C. CFFI is a way for lisp to directly run C functions, and a CFFI wrapper does just that: for every function that exists in the OpenGL API, the same function (with the same arguments) exists in the CFFI OpenGL bindings. Duplicating documentation needlessly is a hack. If your library that you program uses another library, are you required to document that other library as well as your own? No, that library already has documentation. If you want to learn OpenGL, learn a tiny bit of C. You know what? Learn a tiny bit of C either way. It's the foundation at the core of every program written, no matter what language. Plus, OpenGL is a lot more complicated than C, so you've got your work cut out for you if you can't handle C.
