A few more concerns in addition to those I expressed earlier:

- Most MUAs and most other programs that print email messages (say for 
use as evidence in court cases) typically won't display or print 
Expires: header fields because that field has heretofore not been 
regarded as significant.   The reason I'm aware of this is that I've 
sometimes had to explain to courts why a message that's been printed out 
is not an accurate representation of the message that was actually sent, 
because the program that printed out the message tried to be too clever, 
say by converting the original date timezone to a different format.   
And sometimes the precise timestamps matter.

- messages that expire before likely delivery, or only a very short time 
after likely delivery.   Especially
