Well, it was a lost magic bacause it's creators used to be "lost" too, but now we know that some dragons weren't slayed and survived all those years hidden from humans, so I guess if those dragons did it in Fiore they may very well have done in other continents too. And if Alvarez researched on dragon lachrima they could just go mining for it and create some Dragon Slaying supersoldiers.

Also we've (or at least I have) reached a point were DS magic lost all it's mystical/mysterious qualities and just became a strong and rare yet ordinary magic. On the other hand I'd like Alvarez to be the continent where God Slaying magic was created and see some actual backstory to it.
