Looks like CentOS is changing direction - from being a stable binary-compatible RHEL distribution to leading-edge distribution which track Fedora. I guess this is part of IBM's strategy after purchasing of RedHat earlier this year, wanting to eliminate CentOS as competition to their paid-for subscription-based RHEL.
CentOS started out as an free spin of RHEL because not all of use felt the need to pay $500 to Red Hat for hand-held support. I did buy the pre-RHEL Linux releases, but they were much less expensive. Never called for support, though.
CentOS wasn't actually the only such product. I believe that Scientific Linux also did that, but gradually everyone settled on CentOS.
Then Red Hat acquired the CentOS project and I had misgivings, since it's almost inevitable that a commercial concern has different priorities than a mostly-volunteer team.
Then IBM acquired Red Hat, and I became concerned because IBM comes from an era where they had executive washrooms and Linus post-dates that sort of thing, And now, I think we're beginning to see the result.
I would not be surprised to see history repeat itself and a new independent RHEL-clone foundation gets formed. Since this is IBM, I don't expect RHEL to go closed-source as it likely would under, say, Oracle, and in the Linux world, problems tend to find solutions where they can.
Some people, when well-known sources tell them that fire will burn them, don't put their hands in the fire.
Some people, being skeptical, will put their hands in the fire, get burned, and learn not to put their hands in the fire.
And some people, believing that they know better than well-known sources, will claim it's a lie, put their hands in the fire, and continue to scream it's a lie even as their hands burn down to charred stumps.
