It's the other way around.

Any gtkmm/glibmm class that has no public constructor, but which has
public static create() functions, can only be used via RefPtr. You have
no choice.

In general, stuff that derives from Glib::Object must be used via
RefPtr, apart from things that derive from Gtk::Object, which should not
be used via RefPtr.
