i think it gives them a new status quo to play with in a way that is different enough to keep them from going full OMD in the next Crisis.

Bendis has said he wants to show romance, commitment, and marriage in comics isn't and "end" and that you don't need couples to fight and break up to keep drama going in a narrative. To paraphrase his last Word Balloon interview, Lois and Clark would still be fighting the same fights, backing each other up, and enjoying the hell out of every minute they are together. Their marriage would just be a different shape than the traditional family fitting their non-traditional lifestyle.
