In rare cases, you might want to keep `useUnit` calls separate for specific reasons:

```tsx
/* eslint-disable effector/no-multiple-use-unit */
/* eslint-disable effector/prefer-single-binding */
const Component = () => {
const [userStore] = useUnit([$userStore]);

However, even in these cases, consider refactoring to use a single `useUnit` call (or enabling the appropriate options) for better performance and clarity.
