Luna's profile from one of the official Final Fantasy XV book by Square Enix:
LUNAFREYA NOX FLEURET
Born and raised in the province of Tenebrae, Luna is an Oracle. With an inborn ability to speak to the gods, she's had feelings for Noctis ever since they first met in childhood. Unlike the original heroine in FINAL FANTASY XV, Stella Nox Fleuret (since removed), Lunafreya is a strong, independent, determined character, well able to hold her own with the armed guards pointing their weapons at her. She plays a very important role in this universe, since she is not only in FINAL FANTASY XV, but is also in the film KINGSGLAIVE as well.
I mean, why even mentioned Stella under Luna's profile?
Just to point out they removed Stella because she isn't strong compared to Luna?
Stella is not even in the game anymore, so why brought her up?
To remind and disappoint Stella fans?
Stella: "Tabata please"
