@hubert It is not about a naming police, it is about respect to what is already here from traditional and modern chess variants. And paying respect includes noting that the pieces and the names were already used before. A designer may choose to differ and make this explicit in the exposition of his or her game.
Another point addresses potential players: It makes learning a game much easier when pieces with well-known names move as expected from their names.
