I'm not sure I follow you to get to it being a "silly conclusion". As I said, the draft at the time suggests presenting whole messages to the application layer. The parser can't know it has a whole message until it gets the final frame... This could lead to interesting memory usage ;) The protocol provides for a series of infinitely long messages, each separated by a terminator. I don't have a problem with that in itself, but the draft at the time was misleading to suggest otherwise...
