Unclear how to handle GPtrArray

The GPtrArray API has grown from g_ptr_array_new to g_ptr_array_new_with_free_func (in fact it happened 10 years ago) and it seems that all the bindings don't handle this the same way.

Let's take an example:

\**
 * foo_bar_get_icons:
 *
 * Returns: (transfer full) (element-type GThemedIcon): a #GPtrArray of #GThemedIcons
 */
GPtrArray *
foo_bar_get_icons (void)
{
  GPtrArray *array = g_ptr_array_new_with_free_func (g_object_unref);
  GThemedIcon *icon = g_themed_icon_new ("application-xml");
  g_ptr_array_add (array, icon);
  return array;
}

Some claim that (transfer full) is wrong because GPtrArray is owning the element but in fact, we need (transfer full) because if we add a GIcon afterwards, we need to increase its reference count.

A (transfer container) would in fact be something like this:

\**
 * foo_bar_get_apps:
 *
 * Returns: (transfer container) (element-type GApplication): a #GPtrArray of #GApplication
 */
GPtrArray *
foo_bar_get_icons (void)
{
  GPtrArray *array = g_ptr_array_new ();
  GApplication *app = g_application_get_default ();
  g_ptr_array_add (array, app);
  return array;
}

Can all bindings agree on this or is there something that I'm missing?
