We're still issuing SCLs where there is a known need to have multiple versions of immediately available at the same time. The devtoolset falls into this latter category. Thus we ship it as an SCL to allow for parallel installability and usability. -- Brendan Conoboy / RHEL Development Coordinator / Red Hat, Inc.
