+ * The expected result depends on the specific operation, so the GVariant
+ * created by the response processor needs to match the signature given
+ * in this setup.
+ *
+ * TRUE must be returned when the operation is to be considered successful,
+ * and a result (NULL allowed, if no signature specified) is given.
+ *
+ * FALSE must be returned when:
+ *  - A GError is propagated into result_error, which will be treated as a
+ *    critical error and therefore the operation will be aborted.
+ *  - When no result_error is given, to instruct the operation to go on with
+ *    the next scheduled command.
+ *
+ * This setup, therefore allows:
+ *  - Running a single command and processing its result.
+ *  - Running a set of N commands, providing a global result after all have
+ *    been executed.
+ *  - Running a set of N commands out of M (N<M), where the global result is
+ *    obtained without having executed all configured commands.
