This should normally be an edge case that only occurs during the time between a RHEL point release and the corresponding CentOS Linux rebuild. Historically that usually takes about a month. As more and more content is built in CentOS Stream we hope to be able to reduce that. In the case of zstd, the EPEL maintainer jumped the gun and retired the package two months before the RHEL 8.2 release (despite me asking to retire it at 8.2 GA), so there was a longer gap than necessary. https://bugzilla.redhat.com/show_bug.cgi?id=1806759 Regarding using CentOS Stream for your use case, be aware that EPEL is built against RHEL, so it's possible to run into issues where an EPEL package doesn't work on CentOS Stream. This is a known issue that we haven't come to a conclusion yet on how to handle. On a related note, EPEL faces similar challenges when RHEL bumps a library soname. The maintainer has to choose between updating the package to be compatible with RHEL and breaking installation on CentOS, or leaving RHEL installations broken until CentOS catches up. Anecdotally I think most maintainers choose the latter. It's not an exact science.
