It is pretty clever for debug text if, for instance, textures aren't uploading properly. But uh... while it's cute that the OP compares sprite sheets to 16th century manual typesetting, the reality is that it took a printer's assistant an hour to layout a broadsheet of tiny metal slugs on a press, and it takes oh < 10ms to upload a spritesheet to a GPU, which is then infinitely configurable. Not saying it's not a neat trick, it is.
