jemalloc is packaged in the EPEL 10.1/10.2-repos. But could you please also add it for 10.0 / 10z (like for RHEL 10; for the non-stream distros)? It's needed by other commonly used packages like varnish (packaged by their authors). Manually picking the version built for 10.1 works as a workaround, but adding it to 10z-repos would be great.
