Those who do the work, the devs, are free to do whatever they want. However, I and many more are saddened by the loss of traditional Xfce. Xfce 4.14 was already a regression in a way because of immature GTK3 toolkit (right click menus, notification area, color picker etc.). But Xfce devs kept Xfce 4.14 clean. It's good and it isn't really possible to wish for more regarding a GTK3 port.Xfce 4.16 will use "client side decorations" (CSD) or "GtkHeaderBars" which, in practical terms, means that window titles and a close button are shown instead of the regular window manager title bar. All the configuration dialog boxes in 4.16 have these client side decorations thanks to a change in libxfce4ui which makes every application using that library show a GtkHeaderBar instead of regular window title bars.
Xfce 4.16 isn't a problem today, but if you use Linux and Xfce because you LIKE it, then there might be trouble on the horizon. Half the fun is looking forward to improvements. I don't use a single CSD application. Well, except for Chrome from time to time, but Chrome has an option for normal titlebar (no CSD as I understand it).
Question to MX Linux users:
Will you stay with Xfce or use something else (another DE or WM)?
