Titlepage conundrum

Calibre seems to create a titlepage.xhtml file in every book that is really just the cover of the book.

According to Miriam Webster a title page is: "a page of a book bearing the title and usually the names of the author and publisher and the place and sometimes date of publication"

So, I've faithfully changed the name of titlepage.xhtml to cover.xhtml and changed the name of the titlepage from whatever it was index... or something to titlepage.html.

But that's just me, right?
