The resources I've seen aren't totally clear on the permanence of Spiral Energy effects. The early episodes had things revert at the end of battles, but did you ever see anything after the timeskip change like that? Not that I remember. Spiral Nemesis isn't truly defined- it could be the effect of SE usage at any one time exceeding a certain limit, or it could be the cumulative effect of the evolution of all Spiral beings. It was never truly explained, as best I know (though I lean towards SE being permanent, if only to explain why the Anti-Spirals didn't just show up and say 'Hey, if you go around being awesome all the time, you'll make reality collapse in on itself and kill us all. Try not to do that, mmkay?')
As for the point of the concept, it doesn't miss it at all. The Incubators are, if memory serves, basically Utilitarians on the largest scale- the greatest good for the greatest number (all of existence), even if it ends a few planets along the way. Cold logic would be the single greatest factor in any decision they made. Would it require less effort and do less damage to the universe to use the Spirals, in place of witches and magical girls? Yes. How, then? How do they make sure that the Spirals (who can defy the otherwise-valid laws of physics that set the Incubators on their course, the same way magic does) produce enough energy to do what needs doing, especially since they seem to have sworn off excessive SE use by the epilogue of TTGL? Cue unexplained battles- because the simplest way of getting Spirals to make the green stuff is to threaten their lives.
Heck, I could see Kyubey running both gambits at once, and using the Spirals as a Ridiculously Powerful Witch Disposal System. Letting a witch destroy a planet full of potential contractors is wasteful, after all, especially when you can get boatloads of energy out of the next planet over, at the cost of a single teleport.
