Sure
query.runStream() delegates to request.runQueryStream() and typescript users don't have an ability to pass options

export interface RunQueryOptions {
  consistency?: 'strong' | 'eventual';
  gaxOptions?: CallOptions;
  wrapNumbers?: boolean | IntegerTypeCastOptions;
}

in particular the wrapNumbers value, leaving the user no way to handle out of bounds integers.
