Some members of Instance (and perhaps other classes, I have not checked thoroughly) do not display their names as deprecated (with a strike through them) in the object browser. This is (hopefully) a bug, as these members are indeed deprecated, even displaying the ‘deprecated’ text. While this isn’t exactly the top priority, it should be addressed at some point.
