Fedora Server was created originally to be the upstream for RHEL's server configuration, but Red Hat lost interest very early on, so it drifted away from that.
Red Hat doesn't generally invest in any Fedora deliverable except Fedora CoreOS and Fedora Workstation these days. All Fedora deliverables are community driven and community controlled.
Fedora Cloud and Fedora KDE get a lot of work. But since Red Hat doesn't care about them, there's not as much incentive to highlight what they're doing.
But Fedora Cloud is an Edition again in Fedora 37, and Fedora KDE continues to tick along quite nicely.
By that, you mean another server variant than the one day, right? https://getfedora.org/en/server/download/
