How do we know what change issues are currently in progress?
As discussed in DNA, it can be hard to know if any change issues are currently in progress, if you want to execute a change issue of your own or make a deployment. The only way to be sure is to read every comment in all open change issues in https://gitlab.com/gitlab-com/gl-infra/production/issues.
If we made use of workflow labels, as we do in https://gitlab.com/gitlab-com/gl-infra/infrastructure, we could filter down to just the "in progress" ones.
