No, everything is still up for debate, and all options are open. This is people exploring ideas. The Naive DRT is getting some much deserved attention because Jed & Co have put mouse to node graph and put together a real working prototype, but there is absolutely not a consensus around it at this stage.
I’d encourage anyone who has other ideas to please play around with them, and if possible, create working examples. It’s much easier to talk about this stuff when you can point at a picture.
