I haven't designed the protocol myself, but started fancying it some  
years back.

I guess the overall decision was to detach application / system  
indicator from rendering on Ubuntu platform.

E.g. the system indicators (that are special in themselves) run as a  
service and pump their stuff to the renderer. In Unity7 this was some  
gnome-like applet based on GTK. On Unity8, it was some Qt5/QML  
renderer. Furthermore, it was not running on X11 there, but on Mir.  
(Or rather: is running there...).

So cross-desktop-GUI-widget-toolkit was one part of the protocol  
switch decision, I guess. Uniformity another. Making things X11  
independent the next. Just guessing here, but the hints are somehow  
evident.

Is there? I'd be interested to know.

I take this last passage with me from our exchange. Xembed support  
counts (and I have been there, too, even before this exchange).

light+love,
