recently talked to a non-SV software developer friend: yeah, I killed two days making a window show up on top of all others on ubuntu with QT (under KDE, so, a supported business-configuration...). After telling him that this is a standard-feature of most X windows managers and asking, whether he used Wayland (didn't know), we went into functionality. "Yeah, you can enter a command and execute it on a remote machine" - "isn't that what ssh is for and you can do with a 20 line shell-script"" - "Yeah maybe, but some management type developed it, while he was still a grunt so we have to keep it...". I bet, said management type is still bragging about how he introduced convenient remote command execution by writing a QT app and his own server (or maybe he's using telnet...).
