Regarding EPEL and Software Collections

RHEL comes with the scl-utils and scl-utils-build packages — which contain tools for using and building SCLs. These packages appear to function as expected with RHEL and CentOS Stream.

EPEL will not provide SCL support, although it will not prohibit use of the SCL tools provided with RHEL.

EPEL will not provide any SCLs.

For use cases that require the parallel installation of multiple versions of the same component, EPEL recommends the same solution as Fedora in the Fedora Packaging Guidelines.
