It feels kind of pointless since his identity is out there, which means criminals are less scared of him. Remember those two criminals who weren't one bit afraid of the Ghost at first? One of the random conversations he can overhear in Knight is a criminal saying he considered Batman a force of nature and that finding out he was Bruce Wayne ruined it for him. No one's really what you'd call scared of him anymore.
I mean, what's he gonna do? Unmask and start working alongside the police department by their rules, like a certain other billionaire playboy with a bow and arrow did in another DC universe?
