But surely that does not require multiple From lines, like a message 
addressed to many persons does not have multiple To lines, but a To (or 
From) line consisting of a list of addresses.

I've used myself a From (and/or a Reply-To) line listing more than one 
addresses (inserting them at MUA level in the ONLY From line allowed by 
the MUA), when I wanted replies forced to more than one address.
