Hi Lars - No, whatever is returned by getconfignames are created in the 
environment.  From external/ssh:

getconfignames)
        echo "ST_HOSTLIST"
        exit 0
        ;;

and from external/riloe:

if cmd == 'getconfignames':
        for arg in ['RI_HOST', 'RI_PASSWORD']:
            print arg
        sys.exit(0)

The external plugin handler just passes them through unmodified.
