That kind of setting change and growth should be determined by the GMs, not by publishers. It just pisses off players.
The published setting should be pretty static, because once it's at the table, it belongs to the players. Publishing Singularity is fine. Making Singularity the basis for future publications, not fine.
Right now, there's a bunch of "Futures" and your table can pick one or make up your own. Singularity and Wrath of the Ancients are different futures. Whatever outcome of the 5th Frontier War is potentially other splits in the future. I would think it pretty cool if they did a proper player facing Rebellion campaign.
But at no point, imho, should the setting just jump to 1120 with Mongoose's choices for which of those things apply and in what way now being standard in new publications. That's my job as the GM.
