The original use case for SCLs is to provide a way to deliver newer versions of SW in stable distributions like RHEL/CentOS than those available in the core system and make sure system packages and collection packages don't collide in any way (names, libraries, system paths, ...). However as sort of a side effect all other use cases emerge (more stable SW in Fedora, multiple versions of SW, ...). -- Thank you Jan Zeleny Red Hat Software Engineer Brno, Czech Republic
