A random suggestion regarding world consumed by the Prethoryn Swarm.
It looks like there are going to be worlds that are marginally suitable for terraforming in the Utopia expansion (ala. Mars), that are uninhabitable until they are engineered into livable biomes. Is it possible that there could be a large chance of world rendered barren by being consumed by the Prethoryn Swarm could be given this modifier, to make recovering from a bitter fought victory over the swarm a possibility?
