I can understand looking at it from scratch, but BIOS needs to be fast, reliable, absent of errors, and safe. I feel like injecting more complex and graphic-y code will have an effect on that. As we have seen with games, websites, and programs, it's hard to have error-proof code, harder to have permanently error-proof. More code and more interface interaction with a variety of input devices can lead to such issues. I'd hate to see a BIOS update break my hardware in an update just because I can touch and move things on screen.
