This would also be an issue for language bindings. By convention, the
_new() functions are considered as mere C convenience functions, and
many language bindings (and some C applications) just use g_object_new()
directly.

If you want to replace implementations of GTypes, I think it would be
simplest to change the associations inside the GType system.
