This is more a criticism of operators than StatefulSets. The promise of operators is easier automated management of your resources. If the operator can't do basic things like resizing disks, it's flawed and needs to be fixed.
However, I've always been suspicious of operators, so maybe my bias is leaking here. Kubernetes is already a level of abstraction and adding another seems risky and unnecessary.
