There is no such thing as a post Postel world. But handling the input in any other way than crashing or ub IS perfectly Postel. Deciding that nul is invalid data, and refusing to allow it, and refusing to munge the data and proceed based on the munged data that you essentially made up, as long as whatever you did do instead was graceful and intentional, to me that is perfectly Postel.
