The underlying commands can still be logged. Hell, often it is useful to launch a X11 program via a terminal as they will dump useful messages that way. And said output can also be captured in logs elsewhere. One example of such would be SMPlayer. This is a Qt based media player that wrap MPlayer (and more recently the MPlayer fork MPV). But you can still access the MPlayer CLI output by either launching SMPlayer from a terminal, or going opening the log window from one of its menus.
