Passive replenish of depleted planets

The cravers, since in the later game I have found the depleted planets a real problem, should have a passive ability that replenishes a planet's depletion status when the planet is terraformed. It may not be fully repaired but it should at least give a few turns' worth of full resources to perhaps colonise other planets in the system and then move some cravers over there.
In addition to this, based on a comment, overpopulation would lead to depletion points for all other factions too and the terraforming could help them too.
