Should DiffSinger characters be tagged UTAU?

DiffSinger is a Chinese AI-based singing vocal synthesis engine that lets people create their own voicebanks. I guess you could say that its similar to ACE Studio in that aspect. The reason I'm making this thread is to ask how DiffSinger characters should be tagged on Danbooru. Since DiffSinger itself doesn't have a standalone app at the moment (this could change in the future but I don't see it happening for the time being) and is often just integrated into fanmade forks of UTAU, should DiffSinger characters (especially those who have been redesigned for this engine) should be treated like UTAU characters or should a copyright DiffSinger tag be created?. The other option I can think of is continuing to use the UTAU copyright tag but separate this design into a Character_(DiffSinger) tag.

I'd create a separate qualifier for DiffSinger since characters have their own distinct designs for it.

BUR #59478 is pending approval.

create implication gahata_meiji_(diffsinger) -> gahata_meiji

While we're at it maybe it's a good idea to imply these.

BUR #59479 is pending approval.

rename toriko_(39chan) -> toriko_(diffsinger)
mass update toriko_(39chan) utau -> -utau diffsinger
mass update favgroup:55496 -> -39chan

This one's a bit of a mess to explain. Right now her current design is used for both the UTAU and the DiffSinger voicebanks, but the UTAU uses it as a placeholder due to it being finished before the DiffSinger, while it was originally intended for the DiffSinger. So basically the UTAU design for her WILL be replaced at some point.

Also let me get rid of 39chan on every post involving these characters except the one that directly references an event on the site, since we don't use 2channel when tagging Vipperloids.

I've created a tag and a wiki. I personally see DiffSinger as a separate thing from UTAU, and so do most people in the community, despite its integration into OpenUTAU (which is based off UTAU). I felt it was necessary.
