You said it. It's a game in development, so yes, everything is in flux until it gets fixed in the final release.
Or maybe not...
Have you read how J. R. R. Tolkien "developed" his Middle Earth "universe"? Every story of each character was re-written a shit ton of times through several decades until some of them were fixed in The Hobbit...
And then some of them re-written and fixed in a slightly different way in The Lord of the Rings
And some of his stories were never fixed anywhere until his son tacked these stories together somehow in the Silmarillion. Wasn't it described in the introduction part, I kind of remember vaguely? How he found multiple versions of the same story and then multiple versions of another story with some other characters, but the "history" or parts of the story in the first story didn't match the other story and so on.
This is how stories are written. They are in flux until the final version gets published. And sometimes the next story published re-writes some things again.
In Oceans case, the Steam release of a full season seems to be the publishing part that fixes the story in place. Hopefully.
