Red Hatter here and you've hit the nail on the head: For use cases
where you generally only want one version installed at a time, or it
fits nicely in a container, AppStreams are the way to go.  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.
