Second, Shiori herself talked about how she wants to improve her singing and, watching her mess around with the unofficial 3D during the valentine stream, I don't think she will have a problem dancing or otherwise performing during the big 3D events.
Third, I honestly think that Shiori is probably living her best period of her vtuber career in Hololive.
She has contacts and resources to do many projects that she previously could only dream of, and as ridiculous as it sounds I think she also appreciates some of the restrictions she has to operate, due to her paranoia of offending someone often making her suppress what she says/do.
Unless in the future Holo becomes a Niji-tier black agency I don't see her graduating.
