I think we are debating the long-term direction of the project (not the short-term priorities of individual tasks). The decision will have an impact on the scope of Magnum (to be a COE deployment tool or a container lifecycle management service). Maybe your suggestion is not to make such decision in short term? If yes, could you elaborate?
