This was Fedora 31 feature.
I was wondering: Fedora CoreOS actively undoes distribution-wide
changes (at least the two above, I remember lagging with iptables-nft
around Fedora 32). End user may confused, seeing the list of changes
for the release X, but receiving only few of them with edition CoreOS X.
Should such divergence be allowed? Should Fedora CoreOS use the same
version number while not containing all the changes from main Fedora Linux?
I think this is the fundamental difference here, Fedora CoreOS does not have a version number. It has 3 streams, stable, testing and next, these streams are based on a version of Fedora Linux but that should just be a detail that most end users should not have to care about.
Another difference is that Fedora CoreOS has automatic updates and if we want our users to trust these automatic updates we need them to be rock solid. This leads to Fedora CoreOS being more conservative on how changes are rolled out to users, taking the example rolling out cgroups v2 in the Fedora 31 time frame would have broken all users that are using Docker to run their containers and this was not acceptable :-).
If some users are getting confused and get curious about why there are these differences and learn more about how Fedora CoreOS works, that's a good thing IMO :-)
