I agree the 'trick' is not as bad as Thorsten tries to make it in 
practical scene design (i often play with the aspect ratio of the render 
when creating a scene and don't want to be required to modify both 
render parameters and camera settings every time i change it).  But 
automatic aspect ratio is not as easy as it might seem because there are 
at least two ways to implement it (automatic right vector length or 
automatic up vector length).

And note changing the default is a problem in terms of backwards 
compatibility (otherwise the current '1.33' would already have been 
changed).

The most common probably is printing on a printer with anisotropic 
resolution.
