Summary: umbrella list: unsubscribe key public

Initial Comment:
Mailman offers a feature to set up an "umbrella-list", 
which is used if a list just has other lists as members.

Assume we have an umbrella-list U, which has to 
members, X and Y - both are also lists.

Now, cleverly, the monthly password reminders are 
not sent to X and Y, but to "X-owner" and "Y-owner" 
instead, so this information should reach the owners of 
the subscribed lists (sending a password reminder to 
X would mean giving each member of the X list the 
power to unsubscribe X from U etc.).

But: If a member of X or Y opens the member options 
page (http://my.server.net/mailman/options/U/X) and 
clicks on the "unsubscribe" button, the necessary key 
is mailed to X (and not to "X-owner"). This is probably 
not what we want. If the list archive is not private, the 
password is even available to everyone out there.

I don't plan to fix umbrella lists since I want this feature
to go away.  I'd accept a patch though.

Umbrella lists are a hack that will eventually go away. 
Still, if they're there now they should at least be safer. 
Any chance you'd like to generate a patch for this problem?
 If not, I'm lowering the priority because it involves a
soon-to-be deprecated feature.
