CI Coverage has now been restored, however please note that dependency
changes to non-KDE projects will not be possible until the Binary
Factory has been restored to operational condition (as the CI relies
on Craft for non-KDE projects, and it is unable to complete builds due
to the WebRTC/Glib issues).

We are also unable to deploy any new CI nodes for Windows at this time
due to the same issue.

The Binary Factory remains inoperable at this time.
