ConstraintValidator about why is passed ConstraintValidatorContext isValid method, ValidationContext is not

I want to implement a custom annotation check function, check two related fields, based on the value of another field to determine whether this field should be checked as empty, but now I can not get the whole check object, so I can not achieve this custom check, I would like to ask, why the design is like this

version jakarta.validation.validation-api 3.1.0

Start with the ConstraintValidator.isValid method and ConstraintValidatorContext in jakarta.validation.validation-api 3.1.0, then compare them with the requested ValidationContext access. Determine whether the API design supports checking related fields and whether the issue calls for a documented rationale or an API change.
