@kde @gianmarcogg03 you're missing the point. Let me set the stage.
The Modern Linux Desktop Experience^TM:
You have a corporate Linux laptop. You have no local root access. You have no local accounts. You can't boot into single user mode; you can't boot from a rescue disk due to Secure Boot.
It has an automatic VPN back to corporate HQ. You must login with a directory account (LDAP/AD), and it has been a long weekend/vacation and your local credentials cache has expired.
You go to Starbucks and get a coffee, sit down and open your laptop.
But you can't login.
You need to be on a network, but you can't configure the WiFi from the Login Manager.
This is the fake desktop experience. You don't have a desktop, you have a brick. It is completely useless in a very normal scenario -- the exact scenario the EU wants to tackle so businesses can get off Windows.
The Plasma Login Manager is the beginning of solving this type of problem. But making a hard dependency on systemd is stupid.
