I suggest taking every opportunity to ask email client vendors for better
reply options than just "reply" and "reply all".  An email client should
make it easy to reply to the addresses in any or all of the headers of
a message (plus other addresses too).  The Reply-to header is the sender's
suggestion about where replies should be sent, but it is only a suggestion.
The person composing the reply is the best judge of where a reply should
be sent, as only they know what they are putting into the reply.
