Yamato was a last second decision that Oda solely included bc of marketing purposes.
He never intended making her a SH, he just had to throw out some red herrings in order to promote her character/her merchandise.
Once the whole "I'm Oden" shtick got too much it was over anyway.
The international fanbase was at each others throats bc of a small leftist group aggressively pushing their trans-agenda onto Yamato, when it was clear that Oda never intended that for her.
He surely got wind of it (editors tell him all the time about international reactions) and that was the final nail in the coffin.
She is buried.
Ofc she'll make a guest appearance in the final war and help them, but her time as a major character is over.
