Extensibility is [an explicit goal](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 :-)
The downside is its limited integration with other systems and especially databases. If you want to configure qmail, it has to be through text files. But if you want to operate one of the common cases of a relay-only host or a single UNIX host delivering mail to its local users, it works very well.
