Thanks for the breakdown John. I've filed the bug on quickstart [1] and I'll get our guys looking at it on Monday. For now, since the team has diagnosed this is indeed an issue in quickstart relying on deprecated behavior and not an unexpected API compatibility issue, I'd suggest that we make the quickstart tests non-voting until we can provide an updated quickstart version. This should help unblock core and give us time to get a new release out.
