I take `GdkSeat` is available since GTK 3.0? 
https://docs.gtk.org/gdk3/class.Seat.html

But don't we have a minimum set on 3.8.0?

Would this work?

#if GTK_CHECK_VERSION(3, 0, 0)
static GdkSeat * (*_gdk_display_get_default_seat) (GdkDisplay *display);
GdkSeat * wrapped_gdk_display_get_default_seat (GdkDisplay *display)
{...}
#endif

...

#if GTK_CHECK_VERSION(3, 0, 0)
    GdkSeat* seat = 
wrapped_gdk_display_get_default_seat(gdk_window_get_display(window));
    if (seat != NULL && _gdk_seat_grab != NULL) {
        *status = ...
        return TRUE;
    }
#endif
