Nice!  This would even help for gradually porting ancient non-GTK+
software to the new world order.

Your gdk_x11_foreign_new_xdisplay() doesn't emit "display-opened" on the
GdkDisplayManager.  The display *was* already open, but shouldn't the
display manager get to know about this?

GdkDisplay keeps some interesting state (last-clicked-window, button
click times, etc.).  If GTK+ doesn't really own the display, could these
fields get out of sync with reality?  Does it matter?
