- Type of the extension used to store data is a template parameter - The extension is automatically unset when the mode is unset - Handlers inheriting from ParamMode have to provide OnSet() and SerializeParam(); may optionally provide OnUnset() - Transparently handle the case when OnSet() modifies the mode parameter - Remove Channel::custom_mode_params map; ask the mode handlers to serialize their parameters instead
