  # Currently Github actions UI supports no masks to mark matrix jobs as required to pass status checks.
  # This means that every time version of Go, containerd, or OS is changed, a corresponding job should
  # be added to the list of required checks. Which is not very convenient.
  # To workaround this, a special job is added to report statuses of all other jobs, with fixed title.
  # So it needs to be added to the list of required checks only once.
