I've read quite often this statement in IETF discussions. I am not an
implementer but I wonder if this idea of blindly retrieving bits
coming from the newtork is really what the implementers do. Because it
seems there is a security issue here: since the bits come from a
possibly untrusted source (either because it is malicious or because
it is buggy), you surely validate them in some way, first, and
therefore you have to parse the incoming data, no?
