But someone who has never used Darcs before, and thus has never set
$DARCS_EMAIL, $EMAIL, _darcs/prefs/author nor ~/.darcs/author, will
not know that.

The proposed change will not prevent this.  It merely means that you,
the knowledgable darcs user, will need to use that knowledge to do

    echo $OTHEREMAIL >_darcs/prefs/author

instead of requiring a *new* user, who doesn't know what they're doing, to do

    echo $EMAIL >~/.darcs/author

It's this last point we're discussing, and I guess we disagree on that.
