By the way, while debugging the privacy extension for stateless
configuration, I was puzzled that the interface was configured twice.

(once the interface is up), maybe the problem was for interfaces which
are not devices (but from the code it seems it should work for tunnels) ?
So is there still a need for nm to do this stuff (the duplicate
address detection will be done twice, two privacy addresses will
be computed, etc) ?
(see addrconf_notify() in net/ipv6/addrconf.c for details)
