No, they probably wouldn't.  The only caveat is that we do not promise 
not to change how the bounds properties are calculated in future 
OpenSlide releases, so I always encourage applications to use the 
original (physical) coordinate system when storing metadata about ROIs, 
etc.  Cropping by default would make it less obvious that applications 
shouldn't depend on the bounds coordinates being stable.  But the 
uncropped image can be fairly impractical to work with, so this may be a 
losing battle.

It'd be nice to have an option to disable the cropping, though.
