Re: issues 18, 15, 6 -- return routability

 In your previous mail you wrote:

   I think we came to agreement on when we can skip the test 
   completely (by default, do the check; fancier authorization
   is possible but does not have to be standardized). But what
   about the before/after moving the traffic part?
   
=> my opinion is the optional RR check SHOULD be done before but
the recommendation has to be relax (i.e., implementation choice)
when the previous address is known to no more work: there is a
trade-off between waiting for the RR check result and go immediately
to the new and working path.

PS: in an address set management framework, a no more working address
is simply removed from the set.
