There are lots of places that one might want to apply custom presentation if the titles had semantic markup, aren't there? Of course, none of them come to mind right this minute because that's not how my mind works.
Maybe you want to have dates for live bootlegs displayed differently. Maybe you want super-work titles in italics, or omitted entirely.
