One thing to note here: it's now not possible to _request_ to join the
list. If someone wants to join the list, they have to know someone who
is already a member and ask them to join.

It looks like another option is "Anyone on the web can ask" to join.
It's not immediately clear who gets the emails when people ask, but
this seems like it might be a good intermediate position.
