See:

For some history on the issue.

In GTK+-1.2, panes resized with a XOR'ed line.

For GTK+-2.0, we changed it to opaque resizing

My reasoning why it definitely shouldn't be an app property:

 If your app can't handle opaque paned resizing, then
 it won't be able to handle opaque window resizing. And
 opaque window resizing isn't under the app's control.

Should it be a style property or (probably better) GtkSetting
for people with old, slow computers? 

Opaque resizing within a window ends to work a lot _better_ than
opaque resizing of windows (for X scheduling reasons mostly)
and almost everybody uses opaque window resizing these days.

But it's conceivable thing to add if there is sufficient demand.
