From someone else who really dug the relationship, if one were to be going about ending it, the way chosen here wasn't that bad. As I've said before its miles above the tripe we were given in the actual comics, and I'm counting both before the retcon and the actual retcon itself. Both things were awful.
That said I don't expect to see it in this verse again, as they probably plan on marrying Superman to Lois for synergy with Earth-0 in the comics. The hope there would only be in standalone stuff, if they ever do standalone stuff again. But they definitely showed far more respect to their relationship in all facets here due to their continuing strong bond even without the romantic element anymore, something Rebirth never achieved (but of course that wasn't the aim, the order of the day was clearly not respectfully going about an end there), and the current era still isn't.
