It's interesting that you mention that, because while it never quite got to this point for me, I think a lot of the MyrU stories told were kind of downers. I mean they make things look better for the Primeverse, but it's still kind of sad to see things going to hell in some of the others.
Heck, the same book that features "Chimes at Midnight" showcases a Dominion War that spirals even farther out of control than the one we witnessed on DS9.
I don't think this was by any means intentional, but to some degree it implies that the Primeverse really is the best of all possible outcomes, at least for the universe at large. Heck, the Abramsverse has already implied this as well, what with the destruction of Vulcan, London and San Francisco.
Given the events of Destiny, it might be interesting to see a timeline where the NX-02 never met the Caeliar.
