I disagree here. Fedora CoreOS has the Fedora name in it and it should
have the same fundamental features and changes that ship with each
Fedora release. To say it doesn't have a base version and that users
shouldn't care about it is pretty dismissive.
Sorry if that sounded dismissive, but that's really how I feel. I recognize that I have a bias towards thinking that most FCOS users are similar to my profile.
I am a developer and I don't have a strong interest in the OS, I just expect it to work and provide me the tools needed to do my job. To me that's the beauty of FCOS, I get a solid, tested OS that get automated updates and just works, I honestly don't care to know which version of Fedora Linux it is based on or which features it has. I want to spin-up an instance make sure that my application works and forget about it.I also understand that there are other type of users that will care much more about the base OS than me:-).

Confusing and frustrating your users is a bad thing.

I'll echo Neal's sentiment here. This is a cop-out and bad answer.
It is frustrating to consume FCOS only to see features that are in the
current release of Fedora are rolled back. Even in today's FCOS WG
meeting I brought up adding in zswap to FCOS and it is shelved until
Kubernetes adds for support swap enabled systems.
The RHCOS and Openshift teams should be back porting these breaking
changes, so FCOS can look to the future with Fedora. FCOS should not be
shackled by limits imposed by RHCOS/Openshift/Kubernetes.
