But that means that *anybody* can unsubscribe a member, since only
moderation is enabled by the moderation password, not other list
management features such as subscription management.  So there is
apparently no authorization or authentication required to unsubscribe

That may be OK in your environment if nobody knows about it (it's too
much to expect that in a large organization there's neither malice nor
mischief about!), but you may need to change policy if you get a spate
of unexpected unsubscriptions.  You also should avoid "one click"
unsubscription footers.
