CORRECTION: I neglected to make the first version a Markdown message... 
Here's the demo:

Another thing about this "feature" that is definitely bad: a sender can 
copy the cid reference from one message to another and get the image 
rendered like this:

![](cid:F2019F98-AD60-4BFD-B1BE-DD43BEDAE063 at freron.com "Software 
Update.png")

(I am also uneasy about the whole concept of rendering markup in 
text/plain parts on principle,  but I expect that's an unwinnable 
argument)
