☝🏽 that list is only going to grow. See https://github.com/operator-framework/cool-catalog for a more maintainable way to create and maintain this catalog. TLDR: in a separate repository, there's only going to be the index.yaml file and the dockerfile, and then branched for subsequent openshift releases.
