Just recently we have been moving to use names under which characters are known in the original medium, e.g. all recent Genshin Impact aliases. She is called Saber in the game.
I mean sure, let's also move back mordred_(fate) to saber of red, and nero_claudius_(fate) to saber_(fate/extra). And at that point you can also move back to the class names the cast of all games and media.
I think you can realize why we have been moving away from using class names. If it was that easy we wouldn't have this discussion.
She's called by her full name in the original VN, and as far as i know FGO never calls her Saber, so i don't think leaving the tag like this is an option.
