I don't know where you get that reading. The RFC says, essentially, that if you're rejecting the additional addressees but you wish to allow continued deliveries to dribble the message in, you should return 4xx. If you're rejecting it as a policy violation such that messages with over a certain number of recipients will never be accepted by you, you reject it with a 5xx. They're behaving totally consistently with that.
