With Gotham, as much as i wish they stayed around, their histories are too different and are set in way too much of a time bubble for it to work in a chronological world. The same issue preceded Batman: The Animated Series when they would finally merge and expand into the larger DC universe. Considering the Justice League cartoon, the timelessness and anachronistic aesthetic was abandoned in favor of a much more modern outlook. They are well within their rights to do it here, especially since Gotham is already over and they wouldn't be revisiting it after the Crisis, firmly setting it in the Arrowverse without much issue.

Obviously that would mean some characters would overlap or be erased, but it's not like that hasn't happened before, like with Sara Diggle being replaced with John Jr and thus retconning almost every scene with her and replacing her with him.
