I agree that To and CC and not precisely defined.  In my own
mind, the difference does not relate to who should see replies.
I am often interested in replies to messages that I am CCed on.
To me the difference is more in who is expected to act upon
the message.  People in the To field are expected to act, while
people in the CC field are just being informed.
