If I'm to guess, Cover probably wanted to let her debut earlier, but Coco's graduation threw a spanner in their works and they had to delay IRyS' debut to focus on Coco's graduation. IRyS is probably counted as her own "gen", like GAMERS to Gen 3 / 4, or to be more accurate, Mio before Okayu / Korone debuted. Hopefully there might be more members joining Project Hope or Holo VSinger later.
IIRC, Kiara said that she is managed by a different team, under different managers and different rules from HoloEN, so Cover probably has (or had) different plans for her. There would be no point in having different managing team if "VSinger" was just for show. No idea what those plans might be, though
