I'm in the camp that there's a difference between a Warrior of Light and the Warrior of Light.

It's a running theme of this game - Hydaelyn's Chosen were once called the Zodiac Braves, but then any hero became known as a Zodiac Brave. There have been more sets of Braves than there have been Calamities. We saw the same on the First - the first Warrior of Light there was Hydaelyn's chosen, but the word became distorted over time and applied to any hero.

Eorzeans don't know the difference between Echo users that stood with Louisoix at Carteneau and true crystal bearers. Eorzeans don't know the difference between Hydaelyn's chosen (one crystal) and Hydaelyn's champion (six crystals, the ability to interfere with the aetherial realm). Heroes are heroes. Heroes are Warriors of Light. But that doesn't mean we need to take on their ignorance. We know the difference. (...Kinda.)
