That seems the pedantic assertion of someone proposing a bet. Designed 
to be accurate without being illuminating. ("Nah, don't illuminate too 
soon, the chump won't take my bet if I explain myself!")

What about traffic analysis? The size of the the packets can reveal a 
lot. Padding with random data could hide that. Why is that a sin?

Please be illuminating.
