Hi, Matthias. I'm not sure about it either, but one situation where learners or 
users might miss it is when they want to share their work. If their code 
follows the design principles HtDP teaches, the world rendering will rely on a 
single point of control, say the width and/or height of the scene. But those 
are ultimately bound to the particular size of the computer screen on which 
they coded. On the other hand, if they were able to set the relative display 
size as point of control, well written code will behave well on many different 
screens, while not so good code would be penalized when shared. Just a point to 
speak in favor of the inclusion, but there might be more solid reasons to 
reject it.
