Comment(by nickm):

 So to clarify, the desired behavior is that when your IP changes, it
 should be as if you just shut down your router and came back as a new
 router?  That seems suboptimal.

 Perhaps instead if your IP changes, we should treat you as having been
 down since the last time you were observed to be up.  This will count as
 downtime for the purpose of resetting the current MTBF run, and also take
 a little chunk out of WFU.  But maybe it doesn't limit WFU enough.
 Authorities learn about IP changes more frequently than clients, after
 all, so an IP change that is only 15 minutes long from the authorities'
 perspective will be a couple hours from the clients' perspective.

 So maybe we should treat an IP change as if it were equal to automatic
 downtime of the same length as the average propagation time of a server
 descriptor to a client?
