Yes, this EXACTLY. We need CSS libraries that encourage the use of new HTML5 tags. We're no longer living in a world of scrambled DIVs, we have a page structure to follow now. I feel as if this may even be a step backwards, just the third example code in which the Bootstrap version has button while the semantic version is a DIV makes no sense, it's a button, not a DIV.
