This article was written in November 2009 and is 5 years old.
In fact, the very first reply[2] to that patch makes exactly the same point I did above: why not use grub2?

My point wasn't that GRUB 2 did not exist in 2009, but that "Who the hell is still using grub 1?" was not as valid a question then, and is definitely not a reason for you to dismiss the article.
