Cannes themselves are not dangerous, however when being used for the
"root" of a domain is _usually_ a bad idea just for the reasons you
mentioned below.
You seem to have a rather over-extented sense of entitlement towards
telling me that I'm doing it wrong. I hope it makes you feel really
good.
Joshua Smith did not tell you that you are doing it wrong. He pointed
out that CNAMEs are not _always_ a bad thing in general, which was in
response to someone else who seemed to imply they were. He also was
saying browsers do wrong by trying www automatically when the apex
doesn't resolve. He made no comment with respect to the openbsd.org
domain configuration or "operational things".
