Kinda defeats the purpose of replying at all.

Why?? Most mailing lists are a conversation (of sorts). You say one thing 
and I say something relevant to that (like this). Almost all messaging 
happens like that (email, web fora, chat systems, SMS, etc).  Do you want to 
prevent two-way conversation, force every message to me a "new" message, or 

Also, reply-all is a MUA function, not an MTA function, so changing the 
behavior of Mailman is kind of a band-aid solution.

(That aside, you could look at the subject for a "Re:" or similar tag, but 
that's not reliable. You could look for mailman's X-BeenThere or 
X-Mailman-Version headers, which would be better... OTOH, these will prevent 
-all- replies that go to the list, not just reply-all.)
