I think that having two reply commands is precisely what the problem
is.  We should encourage UA designers to fix that.  It is simply not
the case that there are only two reasonable sets of addresses to send a
response to a message to.  Here are reasonable sources for addresses to
respond to:

      Reply-to
      From
      To
      cc
      bcc
      Sender
      Resent-reply-to
      Resent-from
      Resent-to
      Resent-cc
      Resent-bcc
      Resent-sender

If, when I say I want to reply, more UAs simply gave me the list of
addresses above and asked me to specify which ones to use, there
wouldn't be any problem with Reply-to.  There are lots of combinations
of these addresses that make sense in various situations.
