Yes, if we are striving for accuracy then as Baron says there needs to be some sort of different ratios for planetary bombardment.

Facilities and weapon platforms shoud be fairly eacy to destroy from orbit, even with standard weapons, as they are stationary, fairly large targets. Troops, not so easy, but still not all that difficult given a little time, or a lot of ships.

Orbital bombardment, even standard weapons, should degrade planetary conditions somewhat. Although I am not sure I understand the logic for haveing the resource levels of a planet drop as it does now when a colony is glassed.

Population should be fairly easy to kill off at first, but should get steadily more diffucult as the population drops. The Last million or so should be almost impossible to kill from orbit, even with planetary weapons.

The result of all this would be that heavy bombardment would result not in a glassing of a world, but a wiping out of all the infrasturture and defenses and a significant amount of the population. And degrade the conditions so that the survivors have a hard time repopulating it.

Of course this only applies for atmosphere correct planets. If it's a domed colony it should be fairly easy to completely erradicate the population.
