It might be fine, or it might be something you can tune around entirely. I wouldn't call it a deal breaker. You might even be able to convert some essential signals over to the different signaling - I've had to do that with several.
I imagine some "variable" components of the engine, such as VVT, might take it into account by default. It might also affect how the engine drops down to an idle, but if anything this might improve fuel economy - most vehicles idle higher when rolling in neutral vs stationary.
