I disagree as a matter of principle. It is perfectly OK to have specs that are incompatible with each other as long as they are never implemented on the same network. It isn't OK to do that without documenting the incompatibility.
It's clear that this argument doesn't apply to end to end protocols, but strictly to things that have topologically limited scope.
Actually we have plenty of examples of this; they are called routing protocols.
That doesn't settle the issue of whether SEND and NDproxy are or are not incompatible, but I have no problem with the concept that a given (bridged) LAN can only run one of them.
