The original bug report [1] was kept opened mainly due to the lack of adding user functionality in anaconda. This is no more true, anaconda has ability to add an user although it's not enforced.

There are several use cases when local non-root users are not needed at all as others already pointed out. The change itself is simple however the problem is more complex overall. Here are some thoughts I have about the change: - administrators are alerted when they use weak password for root by anaconda - Fedora Workstation and Live installations don't enable sshd.service - even if the default was 'PermitRootLogin without-password' you would need to inject an ssh key and when you are able to inject a key, you are able to change the default configuration - I personally use several Fedora systems without non-root users in local network. - default sudoers uses password of an user for authentication, so even when I have a non-root user in wheel group, I only need one user's password to become root - how much users of these enforced users will be 'user' or 'test'?
