It's preferable to have a confined window manager, instead of one
running in the user domain and that is therefore more easily exploited.

That's the meaning of this patch.

However, I understand we should make sure it works with all window
managers, so I am actually seeking help to test it with window managers
other than gnome-shell.

Because at the moment, the patch is only tested with gnome-shell (to be
honest, not even with gnome-panel/metacity because of a lack of time),
I do not suggest (yet) making them separate optionals. That would
mandate a confined window manager even for setups that have not been
tested yet.
