It would be like saying Flamme and Frieren's flowers growing spell is actually insanely practical for agriculture.
That's why it's bad writing. Instead of wishing for an actually "legendary" spell, Fern picks one that fits the author's writing quirks. Quirkiness trumps quality. I don't like it. I just finished watching a rom-com with Vince Vaughn and Jennifer Aniston that ends with them still broken up, but both happy. I understand the message the writers of the movie want to tell, but I still dislike it, because I wanted them to get back together.
