Oops! In that reply I totally forgot to even relate back to the original post!
I'll just echo what Ashren is saying and point to Roda's picture!
It might not be mentioned but the casting animation is different and just provide a visual on the gemstones. I guess that might be the only 'support' of it being in the game. But as the class information was released by Square Enix I wouldn't say you have to 'retcon' it, really. It's still shown in the game!
Whether everyone will go the same route is a different question, but I've already noticed quite a few people have creative stories about their Carbuncle.
But personally I feel like it's all fine going with the gem is needed, myself!
