They would allow you to create one full screen window and then fail when
you requested more windows or subwindows. I spent a long time looking at
how to add windows to systems that do not support windows (and I have
spent 5 years porting X to many platforms so I know the problem pretty
well) and there is just no reasonable way to support multiple windows on
systems that do not support multiple windows. You would have to add a
windowing system and a window manager in to SDL. Which is something no
one wants and no one is willing to do.
