It's tailored to a specific community, not exclusively, but there's a
definite bias.

Before I retired I was using Scientific Linux for RHEL "compatibility", but it appears to be orphaned with RHEL/CentOS 8:

Scientific Linux is driven by Fermilab's scientific mission and focused on the changing needs of experimental facilities.
Fermilab is looking ahead to DUNE[1] and other future international collaborations. One part of this is unifying our computing platform with collaborating labs and institutions.
Toward that end, we will deploy CentOS 8 in our scientific computing environments rather than develop Scientific Linux 8. We will collaborate with CERN and other labs to help make CentOS an even better platform for high-energy physics computing.
Fermilab will continue to support Scientific Linux 6 and 7 through the remainder of their respective lifecycles. Thank you to all who have contributed to Scientific Linux and who continue to do so.
In the past, CERN has provided scientific packages for CentOS (these also worked in RHEL).
