It might be like you suggested: Foreshadowing, and perhaps for Season Three (even though there's no official confirmation).

Think about it: If Stephanie Brown is there, even if it's just for one episode, it may suggest something. Perhaps there will be another time-skip if another season comes out and Stephanie may become Batgirl while Barbara will become the wheelchair-bound Oracle. You have to remember that Earth-16 is following pre-Flashpoint DC continuity as closely as possible, even though there are slight deviations (such as Red Arrow being a seperate individual from Speedy/Arsenal).
