You are right. I think 'include' doesn't work here because there is a  
notion of choice. If I understand well your example, functors  
wouldn't help here because it is not that you want to get a unified  
interface (frontend) from a specific database implementation  
(backend), but you really want to access database specific features  
via the third party modules, right ?
