[CentOS-devel] info about CR repo

Hello, going through the Open Atrium Portal it seems that the final release could be close.... And at the same time both the 6.3 individual packages and 0-day updates are available. As I saw something similar with 6.2 coming very close to upstream release, I have a question: the CR repo is not something that gets packages available as soon as rpm packages pass QA, correct? So the aim is to avoid CR if possible and use it only if the time between upstream release and CentOS is becoming huge.... Something like a contingency plan and not a planned thing... Am I correct?
