The stable private addresses SHOULD be configured on the interface by
default. The SLAAC addresses MAY be configured on an interface by sysctl,
and I think that for a major release, this shoud be on by default.
Privacy Extensions addresses should also be easily turned on.
The question of which address shoud be used for outgoing connections is
really the question that we are discussing. I'm not even sure how that is
determined these days. And the choice of SLAAC, 7217, privacy extensions,
should probably be settable on a per-application and/or per-user basis.
(Probably, on a process session basis)
