 Replying to [comment:1 Sebastian]:

 nothing significant changed

 Right.  The problem here is that the server descriptor wouldn't change at
 all, but the extra-info descriptor would.  And we need the new server
 descriptor to be referenced from the consensus, or we'll never learn that
 there's a new extra-info descriptor.  So, we'll have to make sure the
 directory authorities accept the new server descriptor whenever the extra-
 info descriptor has new stats.

 One way to achieve this would be to include a timestamp of the last
 written statistics in the server descriptor.

 Are there other ways?
