>I feel like that's irrelevant since that was really just them being told to set it apart from the previous series and wanting to use Nightwing (which is what it always comes back to)
But the audience isn't privy to what's behind the scenes, they just know they saw a series with Nightwing, Batgirl,and Robin. Even with tertiary knowledge of the comics people understand this as a setup that exists, even when it didn't exactly exist in the comics.
