I guess the difference of this suggest shines through more if you are used to craft with the keyboard hot keys for the action bar instead of mouse clicks (or controller). At least for me the craft skills are of left hand but having to click once in the craft window in between is on the mouse, right hand. While this is obviously a quality of life suggestion, for me it would mean I could have coffee mug on my free hand through patch crafting, or something like that as I wouldn't have to touch the mouse throughout multiple crafts.
