You are missing the point. It's not at all about Fedora itself here. What I was trying to say is that today CoreOS (even in) stable is using Linux kernel 4.14.32 (https://coreos.com/releases/) and therefore enabling deployments to use the latest and greatest features, performance optimisations and innovation from the Linux kernel community in enterprise environments. Going back to RHEL kernel would be a major step backwards preventing a wide user base from access to what CoreOS enables them to do today. I genuinely hope that CoreOS folks at RH don't give up on continuing to deliver this sort of innovation. That is all what I was trying to get across.
