Of course, I'm a mere user, not a developer.... but I do read changelogs, and I've never seen it there. I've used a server since sarge, and never had the slightest trace of a GUI installed. I would therefore consider myself a console user, and I always had to use sudo to shutdown or reboot, or su on a new installation. There was never any difference, local or remote. Several years ago, I used to use LXDE on my workstation (between the introductions of Gnome3 and systemd on unstable, to date it) and one day it would not shut down from the desktop applet. I needed to open a terminal to shutdown, and *then* I needed to use sudo and a password. After doing it for a while with no fix, I switched to Xfce, which I've used since, for this precise reason. So it certainly used to work the other way around: DEs had workarounds so that root or sudo was not necessary to power off, but the console command did need root privileges. It may be different now, but it's a long time since I accidentally issued a shutdown command without root privileges, and I'm not going to do it at the moment. -- Joe
