The only real advantage of 8-bit mode would be that the data transfers are faster, so if you need faster updates (i.e. for animations or scrolling displays) then it might make sense to use 8-bit mode.

I'm sure there are use cases. However this driver is asynchronous: it's built for comfort, not for speed ;) I can't recall if the HD44780 can do pixel-wise scrolling which might justify 8-bit mode. But if it can, this driver can't. 4-bit mode is plenty quick enough for banging out a 16 or 24 character line of text.
