It is useful if you want to learn how to create an OS from scratch as a hobby. Modern open source systems like Linux are ridiculously complex and studying Linux kernel code is not something a newcomer should do. Studying old and simple systems like MS DOS is a better alternative, which will help you grasp the basics of how OS functions. And once you have these basics, you can move on to more complex systems.
