Genericity spans binding, notifications and retrieval of a component
from a reader.

For binding and notifications you can do whatever you want inside your
component, because you're provided with the full public IndexReader
interface.
When you retrieve a component, you get your very own interface with
all your needed and totally nongeneric methods.

ObscureComponent c = reader.plugin(ObscureComponent.class);
c.performSomeObscureNonGenericLogic();

This very code can be located both in userland, dealing with custom
components and in coreland, dealing with well-known Lucene core
components.
