@martinthomson requested changes on this pull request.

Ian makes a great point about linkability that I didn't notice the first few times around.

If you migrate to a preferred address that is unique, then you create linkability between network paths.  A client CAN migrate at that point, but in doing so will be linkable.  That's not great.

(To be clear, this is not a consequence of this change, so I will be creating a new issue to track this.  I'm OK if we decide not to fix this in this PR, but I wanted to just put a hold on this issue as it seems like the right place to address that.)
