> 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.
