The example simply points out that your notion of "real world" is
incorrect.

Precisely why I would prefer to have that one glaring exception be
handled manually, instead of having GNUS decide for me.

Uh, why is it "wrong"?  Would you rather that the default was to set
up a situation where a user can reply to a mail only to have it be
delivered to some auto-scanner that sinks it unread?

We agree that the lack of "From:" is an extremely rare incident.  Then
why do you wish that the user forgo the pleasure of handling this
once-in-a-lifetime incident herself?  Besides, like you've shown by
your sendmail example, the message would have to arrive by a really
weird route to not have a From: line in the first place.  Given this,
the envelope sender information is unlikely to be pointing to the
originating host; definitely not an address that should be
auto-selected for replies.
