 Part of 0.2.2.34 was a feature for directory authorities to take the Guard
 flag away from relays that haven't upgraded to 0.2.0.31 or 0.2.2.34 or
 0.2.3.6-alpha, so they can't be used to probe for presence of users who
 haven't upgraded.

 We turned the feature off manually in some of the directory authorities,
 until enough Guards have upgraded that we won't cripple the network.

 We need to look at what fraction of guards have upgraded, and what
 fraction of capacity that represents. Once we see what the upgrade trend
 looks like we can decide when we should flip the switch and take away the
 flag from the unpatched relays.
