Semantic markup is more than just accessibility for me. Even if it doesn't add semantic value to browsers, search engines, or screen readers, it's beneficial to me while developing.

It makes it more readable because you can quickly see the differences in elements instead of just seeing <div> everywhere. It also simplifies and cleans up CSS a bit as you can define more base element styles and then extend them with classes and IDs.

That is what author is saying - "Use the new elements to make your mark-up readable, not for any inherent semantic advantage."

That is exactly the redeeming value of the new semantic elements.
