^ I don't consider either of those examples conclusive. Mordred is Artoria's "son", is she not?
I will only ever refer to Yamato with she/her pronouns. In-universe it might be a bit more nuanced, but it makes sense for characters to refer to Yamato with he/him pronouns if and only if they are either humoring her roleplay/delusion or take her statement about being/becoming Oden at face value (probably just Luffy). All the members of Kaido's crew, regardless of if they call her his son, should refer to her with she/her pronouns as an implicit rejection of her claim to be Oden.
I understand that it's easier and less confusing to use one set of pronouns, especially if using two, one of which is technically inaccurate. However, using he/him universally misrepresents far more characters than using she/her universally.
