I have to disagree with you there, making it compatible would have meant carrying legacy work flows. With a greenfield development they could engineer purely with an eye to the future. Coding for a mix of paths creates a 3 way test problem. You have to test purely legacy, the mix of legacy and new and then just the new. You suddenly have to start coding for runtime depended details.
