Well, I'm not 100% sure about that and it probably heavily depends on whatever the window manager decides to do with decorations anyway, but it seems to be a good heuristic to start with.
After checking with Mutter, Kwin, Openbox and Fvwm, with their default settings, all of these are sending ConfigureNotify events only when decorations are switched on/off entirely and not when single components of a decoration is being changed. Also Fvwm doesn't support dynamically changing decorations anyway.
