I don't think we have long to wait for the next try. He could get it wrong again but given all the feedback and some time to think maybe he's got it right this time (or at least right enough).

That doesn't make sense to me. Surely you want your old code to work with D2.0 but I see much less need to have your shiny new D2.0 code work with D1.0. That kind of like using the C subset of C++ albeit far less extreme.
