There are two key differences that you should be aware of:

1. Because you can inherit from multiple interfaces, you can inherit
implementations from multiple default methods.
2. When you dispatch a call to an inherited method the selection
mechanism is different.  Specifically any class based implementation
of a method will override a default method, even if the default method
is closer in the class hierachy.
