With the retirement of CentOS Linux 8, what is the intended path forward for unofficial user repositories like Fedora Copr or OBS (OpenSuse Build service)? Are they supposed to move to RHEL 8 or CentOS Stream?

For example, Copr has "Epel for CentOS 8" build root for unofficial RPMs for EL8 systems. OBS has CentOS 6-8, but only RHEL 5-7.
