Comment (by nickm):

 0.2.0 is not actually supposed to work nowadays; the issue is that it
 would be Bad Indeed if an 0.2.0 client responded to this change by
 downloading a consensus and a set of certs over and over, rejecting the
 consensus and the certs as invalid every time, and then downloading a new
 set.  A small set of zombie 0.2.0 clients would thereby put an unpleasant
 amount of needless load on the network.

 It's also not enough to test that 0.2.0 doesn't do this with the current
 network; we really need to test that 0.2.0 doesn't have this failure mode
 when confronted with a network containing *only* 2048-bit signing keys.
 Otherwise, things might ''seem'' fine until we drop below 5 1024-bit keys
 out of 9 and all hell breaks loose.

 Other than that, it looks okay to me.
