> At the moment it is possible to add a (by definition required) ConfigurationDependency
to a Component. DM manages the ManagedService registration and relaxes the contraint of having
to implement the interface on your component implementation class, but you do still have to
implement the updated(Dictionary dict) callback on it as it is not possible to delegate this
to a callback handler. I would like to be able to have a way to delegate this to a callback
handler for two main reasons:
> 1) Remove the requirement for implementing the updated(Dictionary dict) signiature in
my business logic. I consider dealing with this delivery mechanism OSGi plumbing that should
not be part of my business logic.
> 2) Allow a factory object to recieve the configuration before the actual factory method
is invoked. This allows the factory to instantiate and configure the eventual service implementation
instance based on configuration data.
