One could build this as a 'side' mechanism into a auto-reply robot
whitelisting mechanism similar to TMDA that IETF seperately
standardizes. The robot-replies sucks for older clients, but work. We
make the the stamp-missing control message machine-readible to make
conforming clients check for other valid stamps (or expend the CPU to
create a new stamp). They're also human-readible telling people to
reply to the robot and complete the handshake.
Okay. Now you're making a purchase decision.
1. A system that does challenge/response and whitelists responders.
2. A system that does challenge/response and whitelists responders,
but also makes it harder for you to send email and requires client
changes, but eventually will be more reliable.
And no, I don't think I'm a pessimist. I just think that companies
make decisions based on short-term economics.
But frankly I think that challenge/response is a non-starter. It
fails with all automated email systems. Worse, it potentially
removes me from mailing lists when it responds (I assume, since it's
a delivery notification, it goes to the envelope from?). So that
means I have to manually check the queue before I allow it to send
the challenge.

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
