you don't seem to understand how bitcoin works. all the nodes on the network must follow the same rules. neither classic nor XT have different consensus rules. They have change proposals, but those can't be activated until the majority of the network agrees to it - basically the miners mining X blocks out of the last 1000. The majority of miners are on core and until that changes, core is the rules.

What I'd love to see is if core would simply stop all development (maybe after the HF and SigWit) and focus 100% on developing an RFC describing the protocol (bugs and all) in detail. Once that's done then we can feel comfortable running other nodes that are compliant and there can be true competition. Then we can work on a steering committee that can manage the development of the protocol. Because 5 developers acting as economists/central bankers is not the way to go.
