Hi,
I really like the idea and planned to file a bug for this already.
Getting the "handle" of a Gdk drawable is probably useful in other
scenarios too. I guess it's also needed for example when you want to
draw via OpenGL on a Gdk drawable.

The only problem is probably the naming of the property: With X11 it's
called XID, with Win32 it's called Handle, with Quartz it probably has
another different name, ...
