  I think there is some slight residual usefulness to designating
vulnerabilities whose first public disclosure results from
discovery/analysis of an active exploit already "in the wild".  ("0 days"
thus being the elapsed time from public disclosure of the vulnerability to
appearance of a live threat exploiting it, a characteristic which an unknown
vulnerability may only aspire to, and a patched one may never live down.)
