I see its more of streamlined and saves CO from any lawsuits in future and he can use his age old "qualifying dates" to determine who are qualified for getting ready with their documents for submitting to NVC.
Now USCIS needs to publish their own VB(www.uscis.gov/visabulletininfo) as how all consular posts abroad publish their own VBs based on CO's VB.
Yes. USCIS might use CO's qualifying dates as acceptance dates or any date which is lesser than CO's acceptance dates and greater than or equal to CO's final action dates, definitely NOT greater than CO's Acceptance dates.
