The full explanation is long and off-topic, but I think one could make 
some certain money by finding someone dumb enough to take bets on RFC 
4865 support being added to a significant fraction of mail servers 
within a decade.

The short version: it's a security nightmare, almost no one wants to use 
it, and no one capable of implementing it in a significant MTA wants to 
do so. A classic case of a "sympathetic magic" RFC.
