Think about a DatabaseConfiguration for example, a load() method isn't 
mandatory since the source of the properties is defined in the 
constructor. But you may want to save the changes to the database at any 
moment by calling save() (or flush).

The loading mechanism is very specific to the implementation, but the 
concept of flushing the properties changed in the memory to the physical 
backend can be generalized to all the configurations. It's not specific 
to file based configurations.
