Extensibility is [an explicit goal](https://github.com/notqmail/notqmail/wiki#goals https://github.com/notqmail/notqmail/wiki#goals), for reasons such as these. If we introduce some more small interfaces -- 1998 qmail was already ripe with examples -- we'll make it easy for anyone to program extensions. If we make it easy for folks to program extensions, we may find there lots of common extensions available. That's the hope, anyway :-)
