The analysis itself could be IMMENSELY useful in things like typesetting. There's a whole assortment of stylistic rules based on rather subtle things (e.g. the space between initials is usually slightly smaller) and they're rather hard to automate. If it were possible to parse and tag text like that, it may give way to advanced typesetting algorithms. By the way, syntax highlighting works for code only as long as you see the same color scheme. If the scheme changes, the benefit is lost.
