The first question should be, why OpenPGP is not used more.  The subject
fulfills an important task: It allows to quickly sort and order
messages.  An encrypted subject would require that you decrypt all
messages even if you are not interested in them.  Further, support for
arbitrary nested MIME structures seems to be broken in some MUAs.


Salam-Shalom,

p.s.
What I do is to use a nonsense subject line for encrypted messages.  This
helps to remember the context of a mail thread while not revealing the
content of the conversation.
