Senders often want to _encourage_ followups and _discourage_ replies.
That doesn't mean senders want to _break_ the reply mechanism.
The reply mechanism is already broken. The way Reply-to is implemented,
it doesn't do the right thing for either "reply to all" or "reply to
author".
There are lots of ways to fix this, but they all involve changing
how user agents work to some degree. To people who are adapted
to the current broken behavior, those changes will be seen as new
broken behavior - at least until they get used to it. The real
question is which approach produces the smoothest transition and
the most favorable end-state.
