I fully agree, but I think it's good to have options on how to approach the issue. Generally, I've referred to OSDev when I need more real-world information on how things tend to work in practice and resources like Phil's when writing a toy operating system. I wouldn't consider Phil's blog a good resource for, e.g., gaining particular insight into how something like the Linux kernel works, but I also don't think Phil intended it for that use.
