This makes it unsuitable for gfx outsourcing work. In my last job (gamedev) people were starting to use more and more of the profiles built-in the image formats we were exporting (we settled on .tiff, but also supported .png, and few others). Though I remember that sometimes previews (or was it layers) saved in the .tiff were making it 10x, 20x (not kidding) times bigger, so a special "save" plugin was done to filter these out, and on regular someone wrote a script to check for such.
