The TL;DR I remember is that over a decade ago, someone who works on Gnome has decided that a machine with only a single user and a single DE does not need to have a “Log Out” button by default - when people mentioned that logging out of a user is still useful to reload settings, the response was that “just rebooting is fine in that case”. Thing is, no one actually noticed those changes until now, because with the X11/Wayland switch, every environment was technically running two DEs and had the logout button. But now with Gnome 50, the switch was completed and the Logout button disappeared for many people (as technically intended, but that feature was implemented so long ago that even a lot of current Gnome devs were confused by it)

Is this a dig at the current minor Gnome 50 drama with the Log-Out button…?
