fix create-t3-app (and trpc) dangerous default?

const t = initTRPC.context<Context>().create({
  transformer: superjson,
  errorFormatter({ shape }) {
    return shape;
  }
});

  // By default, trpc sends the stack trace of the error to the client. Remove
  // these sensitive details before sending to the client.
  errorFormatter({ error, shape }) {
    const safeMessage = error.code === "INTERNAL_SERVER_ERROR" ? "Internal server error" : shape.message;
    const { stack, path, ...safeData } = shape.data;

    return {
      ...shape,
      message: safeMessage,
      data: {
        ...safeData,
      }
    };
