Nonsense. Majority of people submit DS-230 anyways, we all are a lucky bunch I guess. DS-230 is supplementary information, much of it is already submitted in other forms anyways. But the issue here is not DS-230, the real issue is this troll's favorite subject: he is waiting for somebody to ask why. Then he'll go on and on about CP vs. AOS, listing dependents, etc. etc. Listen to him at your own risk.
DS-230 is not supplementary information, it is an application for an immigrant visa. It could revert AOS to CP and it could lead to failure in CP because CP rules are different from AOS. In certain cases you are eligible for AOS, but not for CP. Once you submit DS-230, you might not have a possibility to do AOS any more
