Is loosing the link a sufficient criterion to restart ND? IMHO it is superior
to keep the same IP address (I assume privacy extension enabled) in the same
network if you lose the link artificial.

Environments where the link goes down and up again may suffer from such a
behavior. Maybe a script in Network Manager may be the better place. For me it
sounds like a policy thing which should not handled in the kernel.

But yes Harald, I understand your objection! ;-)
