There's no other list so I think it's right.

Usually I don't need it because unless the viewport is specified by a  
third party library, this information is usually setup by you, hence  
you can store it somewhere for yourself if needed.

Yes it is unimplemented. I don't think it is worth implementing  
because in general querying OpenGL state with glGet (e.g. to get the  
current matrix) should be avoided, it is too slow [1]. It's faster to  
have a mirror of this information on your side.
