Any representation that makes people think "this is a paragraph", "this is a title", "this is a list" and then apply styles to each is an improvement over the current "lets vomit text on a page, then tweak individual sections independently" method endorsed by most word processors.

Tools that do this like (Pandoc being the one I like) do a great job of getting people to think of documents as text that gets styled later.
