Perhaps one reason would be that the freely available JP2K libraries 
do not adequately support these features.  JP2K in TIFF at least 
allows scaling up the image to any image size supported by 
TIFF/BigTIFF (virtually unlimited) by using reasonably sized strips or 
tiles, and allows using any existing TIFF tags.
