 A first step could be updating GladeProject to only use GladeWidget internally
 and then we can update gladeui api to use GladeWidget instead but this means a
 API/ABI break

+Unsupported object classes:
+==========================
+
+Glib
+  * GMenu/GMenuModel (<menu> GtkBuilder element)
+    Because GMenu is in Glib library it can not implement GtkBuildable iface which
+    is in GTK+ this lead to implementing GMenu object construction in GtkBuilder
+    using a custom element <menu>
+    Ideally we should move GtkBuilder and GtkBuildable to Glib and rename them
+    GBuilder and GBuildable so that we can implemet GBuildable in GMenu object
+    A way to avoid this would be to create a new object type in GTK that derives
+    from GMenu say GtkMenuObject (GtkMenu is already taken ;) and make it implement
+    GtkBuildable iface.
+
+GTK+ 3.4
+
+  * GtkApplication (add buildable iface to support GMenuModel?¿)
+
+GTK+ 3.10
+
+  * GtkHeaderBar
+  * GtkSearchBar
+  * GtkStack
+  * GtkStackSwitcher
+
+GTK+ 3.12
+
+  * GtkActionBar
+  * GtkFlowBox
+  * GtkPopover
