At some point, we might want to add a "rev_on_disk" field to the revisions table, and move the text of revisions older than, say, 3 month to the file system (file name generated through article and revision ID).
If and when you are going to do this, hopefully you are going to use the page_id, not the article title, as otherwise you will have to rename potentially arbitrary amounts of files upon a page move, and you will potentially make it impossible to run on Windows due to its filename character restrictions.
