That is something I am quite comfortable with.  Any data that is
received doesn't need to be discarded outright, some of it can be held
for a short time in anticipation of being able to authenticate it.
That's likely critical for early call performance.  This is especially
bad for video where a) you can't send a lot, b) you need to send a
lot, and c) everything else that follows is dependent on that early
data.
