Based on my understanding, there is no "direct" benefit for the casual editor/reader. This is more of a back-end change that will streamline future upgrades to the page structure and design by making it easier for Wikia staff to design and dimension changes to various page components (e.g. the headers and rail). The only outcomes of this change for the reader is likely to be fewer bugs when viewing pages.
