Yes, that one.

Well, mainly all the features only available to GLib.Object, which are:
 - signals (delegates should still work, though, so you can still define
   hooks manually)
 - properties (those with get/set -- plain fields of course work)
 - interfaces
Than some other things depend of glib/gobject infrastructure, which are:
 - exceptions
 - the new async stuff
 - dbus binding

There is a plan for new support runtime called dova, that should provide most
of the features while being lighter than glib, but I don't think any
timeframe for it was announced.
