In my opinion, a widget and its contents should always be visible 
BY DEFAULT, if its sensitiveness is set to false. There should 
be a simple way to make things invisible, but that should be 
a programmer's decision, not a decision imposed by the toolkit.

You said that in GtkEntry the text is still visible after
setting its sensitiveness to false. I can add other examples: 

1) in a drawing_area with sensitiveness set to FALSE, the 
picture is still visible, though its events are frozen
(just tested this myself).

2) if the sensitiveness of a file_selection_widget is set to 
FALSE, we can still see the files, directories, etc...
nothing is hidden, just turns... insensitive...
(again, just checked this)

3) in an option menu, a menu item with sensitiveness FALSE 
is still visible.
etc...

So, in my opinion, the GtkEntry behaviour is right, 
the Gtktext behaviour is wrong.

(This does NOT mean that Gtkentry text should always be visible 
with sensitiveness set to FALSE, in most situations the answer 
is no. I always put a gtk_entry_set_text (entry, "")
before a gtk_widget_set_sensitive (entry, FALSE))
