> Currently we have the following setup in c2 component manifest model:
> _ExtensionComponent_ - base class where type and bundle info exist
> _ConfigurableComponentDefinition_ - interface for property related methods
> _ProcessorDefinition extends ExtensionComponent implements ConfigurableComponentDefinition_
> This makes it hard to write generic code for a configurable extension, meaning a component that has type/bundle info AND configurable properties.
> If you want to declare a generic type you have to do something like:
> _T extends ExtensionComponent & ConfigurableComponentDefinition_
> We can improve this by introducing an abstract class that extends ExtensionComponent and implements ConfigurableComponentDefintiion, then make the definitions for processor, controller service, and reporting task extend this new class.
> A similar scenario exists in the Versioned component model.
