I also have a feeling it will only be minor changes if any. Obviously his writer has a prefference for this type of content - which is actually fine. Representation is fine.

Should it have been a character added as Fanservice? No, that should have been a romance as approachable for as many as possible since it was so widely requested

Should it have been added? Sure, with a character designed fdor it from the beginning and with the level of detail it deserved.
