Practical question... (Theoretical types can stick their fingers in
their ears while I ask) how many MTAs (besides Qmail with
"Return-Path" headers) make this info available to the MUA ?  

Exim can, but requires a non-default (at least under Debian/Linux)
configfile option.

And in those cases, how many MUAs would know about it ?  

Proximal to zero.

The roblem with an end-user C/R system is that the MUA usually only
has the "From:" header to work with and Joe Average (as opposed to the
average subscriber to this list) doesn't have a clue about the
difference between "From:" and "MAIL FROM:"

True, unless the C?R system it set up server-side, or by someone
server-side proficient (which TMDA essentially requires).
