From what people who had seen the mod page were saying when this all started blowing up, was that it was removed not for what the mod did, but for what the author of the mod put in the mod description page (basically full of racist, sexist, homo and transphobic bullshit), which was a violation of their rules. Plenty of other mods that remove the pronouns option still exist on Nexus, but without the bigotry clearly laid down in their descriptions.
