Why?  As I recall the history here, it has only been fairly recent that many
operating systems would support files larger than 2 gig.  AFAIK Microsoft's
FAT filesystems are all limited to 2 gig file size limits.  So it might be the
case that the majority of filesystems currently in use still have this limit....
