Why not just yum install sccache?

I checked: sccache isn’t in EPEL 8/9 (manylinux_2_28 is RHEL 8–based). Only ccache is there. Fedora has rust-sccache but that’s not in EPEL, so we’re installing the official GitHub release to get a current sccache (e.g. 0.14.0). See https://repology.org/project/sccache/versions — there’s no EPEL 8/9 entry for sccache.
