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

[Sheldon66-Huang]

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
