Awful idea. Just awful. The reason for splitting content (+hooks in form of CSS classes) and presentation is to make problem space smaller. If you say that HTML is now concerned with presentation too, you are basically going back to inline styles. And yes, I would prefer style "font-size: 10px" to class "fs10" anytime. At least I don't need to learn new classes with every single codebase I come across. There is a reason developers get emotional when someone tries to defend ideas like this - it's not because we don't understand, it's because we do, and we've been there. The location of the CSS is a solved problem, just let it be.
