  // with it.

  // Add the owner of the app (Drupal user id) to ensure when the Drupal user
  // gets deleted then _all_ its cached developer app data gets purged along
  // with it. (The additional cache tag by developer id should be enough
  // though.)
  // Note: This also invalidates cached app data when a user gets updated
  // which might be even beneficial for us. Create a custom solution if this
  // default behavior becomes a bottleneck.
