Wouldn't that create problems with mailing lists(1)?  Here's an
example from a few years ago(2):

	Return-Path: [email protected]
	...
	From: From: Mark Horn <[email protected]>
	To: [email protected]

(1) Yes, I know that the *best* way to read mailing lists is GMANE,
    but not all list owners agree.
(2) ...back when I actually subscribed to the TMDA lists instead
    of using GMANE.
