I assume it was a theoretical analysis...
With sendmail-user-agent, mail-setup inserts "Cc" and "In-reply-to"
directly (apparently the latter should be "In-Reply-To"?), ignoring the
case passed via other-headers.
With message-user-agent, message-mail explicitly uses capitalize on all
headers.
I suppose there's no guarantee that some other mail-user-agent won't use
the headers as supplied, but perhaps that would be a bug in the
user-agent?
