Does anyone else on this list see a problem?
Yes. Personally I don't care, but I see the problem.
For example, some people sort mail into folders on delivery. If replies
to a message from me contains header fields such as "To: ... arnt" or
"Cc: ... arnt", that means I could file them where I'll notice them.
The same thing could be achieved with a little bit of references parsing
and a database lookup, but the software people use now can't do that.
(procmail and various sieve implementations are typical examples.)
