Ward and John write about the Chorus of Voices. I don't think that's a good description of what fedwiki is. In one respect, John and Ward are right about the chorus obscuring individual identity. If you can hear individual voices in a chorus, they're doing it wrong.
The chorus also subsumes individual autonomy. Mot of the time, everyone is singing one of a handful of parts. There are rare instances , like Tallis's Spem in Alium, where each singer is doing something individually distinct, but, even in those cases, the singer's autonomy is tightly circumscribed by the score.
Perhaps something like a jazz combo is a better analogy. There's a shared framework, but the individual participant has tremendous flexibility within that framework.
Another possibility is to look at some Indigenous ways of singing as ways of thinking about SFW. See: Yoiking.
