I found it all kind of ridiculous, but my solution was to graduate 2 years early, not to fuck with the administration. Didn't seem worth the time or energy.
A better idea would be to create a duplicate A record, not a CNAME. CNAMEs are really meant for something else.
Although in practice, lots of people do use CNAMEs for the purpose you are suggesting.
