Somebody pointed out about the CNAME available on Cloudflare. I never knew that and i checked out the article. The First paragraph:

"CNAME setup is a manual process generally available to paid CloudFlare plans only. If you are interested in testing CNAME setup, please contact CloudFlare first with the domain you would like to test CNAME with. Please specifically mention CNAME Setup in the subject field for faster review. Allowing for CNAME setup is entirely at the discretion of CloudFlare."

So NO: This isn't even a features at all. They made it as hard as possible to set this up and will grant you the use of it as they like.
