Rawhide is the development branch of Fedora. Terra is a community rolling-release repository that provides additional software on top of Fedora, for both the Rawhide and stable versions of Fedora. They're not directly comparable.

Sure they are. Rawhide is the official community-driven rolling release for the latest of Fedora. If you want to get some package into Fedora (and thus RHEL), put it into Rawhide, not Terra.
