In Detective Comics #673 Batman imagines a case for Stephanie's costume in the Batcave. It may not even be real, but it does suggest that deep down Bats thinks she deserves one, and in a wider context acknowledges the same fact, despite Dan Didio's rather poor editorial joke about her not getting one: this presumably being a hint about the current rash of appearances by Spoiler in several Bat-titles.
This was an entirely arbitary goal set by girl-wonder when it was first formed. Only an idiot would assume that this means the battle is over. But it gives the guys at g-w a reason to celebrate.
