The remote backend is superseded by ethclient. The nil backend's stated purpose was to enable testing of accounts/abi/bind. None of its methods actually worked. A much simpler way to get a crashing backend is to simply pass nil as the backend. With a one-line change to the generator (removing two explicit interface assertions), passing nil actually works. Removing these backends means that less changes are required later.
