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, ...).
