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.
