...PLUS the sender.  Reply sends to just the sender, Reply-to-all adds all 
the recipients.  It is the definition of "sender" that causes the problem 
here.

Not necessarily.  The "To:" address is often just a fake, like "Recipient 
list suppressed".

That's just not true.  The Sender: header is supposed to indicate the valid 
mailbox of the person/bot that actually transmitted the message.

It's easy enough to look it up.  Anyone interested enough in e-mail to be 
part of this list should probably have a copy on their bookshelf.

"Sender" is indeed a valid RFC-2822 header.  In fact, its use is encouraged 
if the person who SENT the message is different from the person who WROTE the 
message.
