Ideally, every 'dynamic feature' could be built in directly to the mongo binaries (embedded), not built at all (no support), or built as a plugin. Linux does something similar with its kernel, where features can be specified as 'yes|no|plugin'. We envision something similar: for SSL, for instance, SSL support could be selected via --with-ssl=[yes|no|plugin].

This would be very helpful for users who are building from source and don't need the additional complexity or failure modes of using plugins.
