> Currently processors cannot reference controller services through parameters.
> While this has security reasons (apart from the technical challenges), flow definition reusability would be greatly enhanced if users could predefine controller services and control which one to use (if at all) through parameters. This way the flow itself could be treated as static and all aspects of the configuration could be managed without the need to change it.
> Security concerns need to be carefully handled whenever the parameter (referencing a controller service), or the processor property (using such a parameter), changes.
