The proposal (140) doesn't appear to discuss the client
fingerprintability aspect of this: they reveal the last time they used
Tor (if recentish). Say you're a mobile client that gets a dynamic IP
address. With this, you reveal that you probably aren't or maybe are
the same person that was last seen over there at that particular time.
What are the implications here?
