Tomasi wrote that line in both the comic and now the animation. I don't think it's anything deeper than a writer liking the phrase for an emotional but tragic scene of Clark dying in the arms of the woman he loves. Had it been Lana or Lori or some other woman that meant the world to him, I wouldn't be shocked to see that line used in a similar scene. It's odd to condemn a fanbase when they had nothing to do with writing it.
