Because changing things out is hard and the benefit of pulling in that much more code and complexity is dubious. It seems like you could implement a p2p solution as a pull through registry... as in host a registry (even per node if you like) that Docker will use as a pull through cache, still speak the same distribution protocol, but have the registry use p2p to get the content.
