I've had a use for it, porting existing dictionary code to a BTree.  It
was reasonably easy to simulate but did make the code slightly less
readable to the person who originally wrote the code with setdefault.
They were suprised I took such a "naive" approach until I told them
BTrees had no setdefault.
