Religious as in there are strongly-held beliefs on both sides, but only
one is really based in logic and common sense? :)

Yes, it's Reply-To: that people get defensive about changing, but...

... that isn't really the point. People *do* talk about 'freedom', but
it's the freedom to have their mail client actually do as they ask it. 

A mail client has a private 'Reply' button, and a public 'Reply All'
button. Each has a clear and simple function.

If the list abuses the Reply-To: field, that overrides the behaviour of
the private Reply button, hijacking it to send a public reply to the
list. So the recipients' freedom is taken away from them ? it's like
breaking into their computer and hacking their mail client so that
*both* buttons do the same thing ? occasionally leading to a *highly*
embarrassing event when private emails are accidentally sent to the
list.

If the list *doesn't* abuse the Reply-To: field, then the mail client
does the right thing. The private Reply, and the public Reply All
buttons, both do precisely what they should.

The main reason people advocate for munging Reply-To: is usually that
"list members are too dim to press the right button".

Which aside from being fairly insulting, is kind of a self-fulfilling
prophecy ? because for those who genuinely are that unsophisticated, by
hacking their mail clients to behave inconsistently, you actually
*reduce* their chances of understanding it all. The private/public reply
button concept is *so* simple, that I'd suggest the *main* reason people
have problems with it is because of misguided Reply-To: headers changing
the behaviour and making it inconsistent.

It should also be noted that the failure mode when you do the hack can
sometimes be catastrophic, as public postings can never be undone. The
failure mode if someone accidentally hits the wrong button, as well as
being entirely their own fault, is very minor ? all they need to do is
resend the message.

And in the general case, if someone isn't *even* paying enough attention
to press the right button, sometimes there is *benefit* in having their
messages not reach the list until the coffee has kicked in and they're a
little more awake. They can edit the message before they resend it :)

There is little benefit in a Reply-To: header, and it is actually
*counter-productive* in the long run for the one case where it has any
dubious logic at all.
