The notion of the "sender" may not be well-defined from gnupg's
point of view.  More precisely, it only makes sense with signed and
encrypted messages.

Anyway, your proposition would produce warnings when encountering
messages which are commonly created by mail user agents such as
mutt, or by the Windows and Macintosh versions of PGP when the
sender sends messages to various recipients.

So, while the idea might be nice, it won't work in practice.
