I'm unable to follow the logic here. Why does this follow? And why would it make a difference, since non-copyvios would be rejected by the CP process anyway? If a page is a copyvio then it _should_ go on CP, if it's not a copyvio then it shouldn't. The means used to remove the articles don't matter.
I'm not sure what you mean by "tactic of last resort", either. Do you mean that people who are dead-set on deleting an article will try accusing it of being a copyvio if a VfD fails to remove it, even if it's not? That's bad behavior, again regardless of the means used to remove the articles.
It has been known. It will happen again.
