unhandled validation pattern change

100%

    1. install a CRD where one of the fields has a validation pattern
    2. upgrade the CRD to a version where the field no longer has a pattern
    

v1alpha1: ^.spec.central.persistence.persistentVolumeClaim.size: unhandled: unhandled changes found (Pattern `^(\+|-)?(([0-9]+(\.[0-9]*)?)|(\.[0-9]+))(([KMGTPE]i)|[numkMGTPE]|([eE](\+|-)?(([0-9]+(\.[0-9]*)?)|(\.[0-9]+))))?$` -> "")
    

something that does not mention "unhandled"    

Not sure what the rules should be, as it might be hard to programatically establish whether the change relaxes the validation or makes it stricter (or both!).
FTR this particular change was a mistake, as it is a long-unused field and leaving the validation around would have no bad consequences.
