Yeah, so? It's a user mistake, it's up to the user how to deal with it.

No, as I said before, the Reply-To problem is *orthogonal*.

See, I'm _subscribed_, right?

When I search for 'list:users.lists.fedoraproject.org
to:felipe.contreras' I don't find anything (well, I actually I see one
mail because Alan Cox ignored the Reply-To header).

OTOH 'list:linux-kernel.vger.kernel.org to:felipe.contreras' works fine.

Also, what happens if I choose to stay subscribed, but decide to turn
mail delivery off? Well, I can send mails, but I will not get the
replies.

So no, the drawbacks of Reply-To munging are not limited to non-subscribers.

And that's the only mail the person will receive. The list server will
see, oh, that mail was sent directly, so I'm not going to do it again.

Did you even read the description?

Avoid duplicate copies of messages?
When you are listed explicitly in the To: or Cc: headers of a list
message, you can opt to not receive another copy from the mailing
list. Select Yes to avoid receiving copies from the mailing list;
select No to receive copies.

If the list has member personalized messages enabled, and you elect to
receive copies, every copy will have a X-Mailman-Copy: yes header
added to it.

No, the people who complain (if the ml uses mailman (not everyone
does)) have it *off*.

Fedora mailing lists (or at lest this one) has it on by default;
that's why you would not see this problem (in case somebody overrides
the Reply-To header).
