The new configuration stuff is neutral in regards to multiple external configuration files. It doesn't preclude the possibility, but I don't see it encouraging it either. The default is to use the main configuration file.

All the work I did was to make it possible for each module to have its own defaults.

In order to use multiple configuration files someone would have to override `public void init()` on their subclass of `Configuration`.

I don't necessarily think multiple configuration files would be a mistake or a problem, but in order to use them you would have to go a bit out of your way.
