Hoshimachi Suisei and Studio Stellar

So, as of 22 March, 2026 Hoshimachi Suisei has branched out of Hololive into her own studio under the Studio Stellar branding. It's still under Cover Corp, but is distinctly not under the Hololive label, which even Hololive Dev Is cannot claim.

Should we make a new tag for this in similar vein to DEV_IS, and if so, should Suisei posts from 22 March and forward be tagged as such when appropriate?

I really do not see the point of giving Suisei her own solo copytag.

I don't think we ever had a separate tag for INNK Music, right? I think we can treat this similarly and keep her under the Hololive tag considering she still has ホロライブ in her bio.

She said in a Q&A that Studio Stellar is independent from Cover Corp but she will still remain a full hololive member, so if anything case she should be tagged both hololive and Studio Stellar, but unless she does something like debuting new members under Studio Stellar, I really don't see a point of making a coputag that is just going to be a synonym for hoshimachi suisei
