I typically avoid modifying the behavior (and hence o/p) of existing commands; in my view a particular command (and options etc) and the resulting o/p format are part of the API "contract", hence simply modifying the -verbose option to
emit this additional field, would break the existing "contract", which in the case of a programmatic parser client would 
most likely cause failures.

IMO adding a new option preserves the existing contract while providing the additional metadata for new consumers
aware of its availability and desirous of its content.
