Mails are allowed to have multiple addresses in the from header as

Has anyone seen such a user agent?
Mail.app on OS X displays multiple From: addresses correctly, highlights
them as separate addresses with separate context menus correctly.
Reply and Reply All respond to just the first of the From: addresses,
while Reply to Sender replies to both of them.
So it seems to work fine, though given I don't really understand the
intended semantics I'm not sure if they match that.
Functionally, should multiple from
addresses be considered a deprecated feature?
I'm a bit vague on what their intended use is/was.
