With the majority of the corruption in the Gotham police Department now removed, the cops will have their job cut out for them in preventing a new wave of crime. By taking this method, both the Penguin and GCPD shows will be able to experience the 2 aspects of Gotham, depicting the city's restoration without the need for Batman to be present. Then, by the moment The Batman 2 comes out, Gotham will be fully operational. Even if the GCPD series ends up being a prequel rather than a sequel to The Batman, it can use the time to establish the court of Owls so that the organisation doesn't appear out of nowhere in the sequel (or third film).
