Comment(by arma):

 Belief 1: The end-goal here is to dump everything related to v2 statuses
 -- don't generate them, don't serve them, don't store them, etc.

 Belief 2: The only reason we haven't already is that we don't know what
 chaos will ensue from old Tors that freak out when things change.

 So we could do some change that we think is less likely to cause chaos (I
 think "Don't serve networkstatuses older than X hours" is such a change).

 Or we could do a more serious change ("stop serving v2 statuses").

 In either case, we'll want to see if chaos ensues, and have a simple way
 of rolling back if it does.

 I'm inclined to try the more serious change, in case it works.
