The part of the man page that can be considered a spec is the part that describes the behaviour, and the arguments in favor of always using /dev/urandom over /dev/random are based on the described blocking behaviour. I'm fairly sure they would have to change the nature of /dev/urandom in such a way as would invalidate the other parts of the documentation in order to make the erroneous parts of the man page contain valid concerns.
