There are a lot of use cases for baking binary data directly into the program, especially in embedded applications. For instance, if you are writing a bootloader for a device that has some kind of display you might want to include a splash screen, or a font to be able to show error messages before a filesystem or an external storage medium is initialized. Similarly, on a microcontroller with no external storage at all you need to embed all your assets into the binary; the current way to do that is to either use whatever non-standard tools the manufacturer's proprietary toolchain provides, or to use xxd to (inefficiently) generate a huge C source file from the contents of the binary file. Both require custom build steps and neither is ideal.
