I don't really think the side stories will never be animated. They introduce characters and elements that are important for the main stories: Brunhild and Gungnir (Kanzaki SS), Leivinia and the DCS, and the concept of Dvergr (Stiyl SS), Xochitl meeting Saten and Mikoto (Liberal Arts City). I think they'll get at least OVAs. They could even be added in the main anime series to make more of them.
