Okay then. Lets make it a bit more direct. We write in the Bible today that Talon company is decended from a group like Blackwater. Ex Military officers operating as civilian contractors, those that exist today are the decendants from those helping establish military law in Toronto.
Lets say then in Fallout 6, we've got a great idea that talon company could slide right into. Problem is, is that the Civilian Military contractors idea isn't going to work, neither is the Canadian Connection - they're now decended from an active military unit guarding fort knox.
Whilst we can say that "The bible can be changed", the result would be accusations of breaking the established canon here on this very forum, NMA, and well everywhere else. It would also invalidate the point of the bible - its not really a bible if its just a few unused ideas that can be contradicted at a moments notice.
I agree that "Behind the scenes" stuff is good, and if devs want to publish a dissued concept for a location or quest like we saw with van buren, great, publish away. But it should be clearly understood to be non-canon until confirmed (and the Bible name not used).
Then the bible should be respected and followed, if the new idea don't fit then they can work with what they have instead.
Only way to allow complete artistic freedom is to set a game far away from the others and only have new stuff.
So long as there is old stuff there are old rules that need to be followed.
Might limit them somewhat but this isn't some kind of personal playground, the devs better damn well follow the lore.
Whether it's from a game, a comic or an online bible.
And hell, I consider it better writing if a writer can take previous work and while still following it put his/her own spin on it.
Gonna stop nagging about it now though, opinions differ.
