The increasing use of bots may be due to an increased use of Infra-as-codes or other integrations. Git is no longer a mere code management system. It's already part of the production infrastructure.
In the current company, we have github-action based CI/CD. On top of that, we have config management via git, deployment via Pulumi (also on git). And we are also exploring describing k8s controller workflows with yaml configs.
It seems that GitHub is really in a good place for becoming a company for "production infrastructure minus codes". I'm wondering if there'll be some competitors in this field.
