There are also for example in gdal_translate also "xoff yoff xsize 
ysize", i.e., (xmin, ymin, xmax-xmin, ymax-ymin) and "ulx uly lrx lry", 
i.e., (xmin, ymax, xmax, ymin).

I guess the main reason is that changing the interface is a major 
change. So, perhaps this could be put on the list of things to consider 
changing in GDAL 3.0.
