What's the point of decision behind getFieldState requiring render subscription?

[Noitidart]

Whenever I reach for getFieldState is in a place I use form.getValues. Getting values does not require render subscription. Is it possible to make getFieldState behave the same? Is it possible to gurantee that getFieldState is in sync with getValues? I currently use getValues, but have to wait for a re-render to get latest valid state, or I have to opt to re-running expensive form.trigger validation.

Another place is in a dependent validation in field Y. In this config I get the value of field X, but if it's not valid, I want to ignore:

const FieldYConfig = {
  validate: {
    isDoubleX: value => {
      const x = form.getValues('x');
      const isXValid = form.getFieldState('x'); // This does not work
      if (!isXValid) {
        return 'X must be valid first';
      }
    }
  }
}
