/**
 * This component removes redundancy by declaring a prefix that is shared by all enclosed form-related components.
 * It might be helpful when the data structure of a list's items does not correspond with the individual list item's
 * form structure.
 *
 * @beta
 * @since 2.43.0
 * @example ```
 * // For data of structure
 *    {
 *       subForm: { foo: boolean, bar: string };
 *       flag: boolean;
 *       tag: string;
 *    }
 * // Because we use ConfigurationForm we get and update the whole object.
 * // We only want to create a form for 'subForm' without having to repeat it for every subField
 * // while keeping the original data structure for the whole form. *
 *
 * // Using this component we can write:
 * <Form.PathContext path="subForm">
 *   <Form.Input name="foo" />
 *   <Form.Checkbox name="bar" />
 * </Form.PathContext>
 *
 * // Instead of
 *
 * <Form.Input name="subForm.foo" />
 * <Form.Checkbox name="subForm.bar" />
 *
 * // This pattern becomes useful in complex or large forms.
 * ```
