Well, technically the API is still available pretty much everywhere (be it directly or via a wrapper library) and most hardware still has support for drawing lines, so it is still easy in current days to do things like this too :-P. I'm using it all the time when i want to draw lines in 3D. (though as far as lines and OpenGL is concerned i remember reading ages ago that not even SGI's implementation had full support for everything OpenGL was supposedly able to do)
