I have asked for that before. At the last Linuxtag in Berlin noone from KDE or 
the BSI (which has paid for the crypto integration of KMail) accepted this as 
a problem which should be solved...

In addition to what you just described I would like to have standardized dummy 
entries for the to and from field (probably seldom used but little effort to 
cover them, too) and the subject. That way you can also encrypt the headers.
