As #action-ed in yesterday's QA meeting[1], I have added the proposal as-written to the Basic release criteria[2].
If a utility for creating user accounts and other configuration is configured to launch, it must be visible within 10 seconds of the first boot reaching the launch point.
The most significant feedback was that we should also block on the sad face. As Adam noted, we can consider that under the Final criterion
There must be no SELinux denial notifications or crash notifications on boot of or during installation from a release-blocking live image, or at first login after a default install of a release-blocking desktop.
Of course, we can always adjust this criterion in the future.
