GNOME OS uses BuildStream and as a result has no concept of packages at all and no relationship to any distro, KDE Linux is based on Arch. There is no relationship between the two. GNOME OS used to be OSTree based but switched to systemd-sysupdate a while ago.
CoreOS is in a weird space. It's been desperately playing catch up with it's sibling products for the last few years, but it also is where a lot of the Fedora/RHEL developers in this space are focused primarily.
