Besides a pathological need to be clever? ;) The former keeps the
recursive relationship intact if you define a class that inherits from
recursivedefaultdict. The latter would create the nested entries of the
derived class as "vanilla" recursivedefaultdicts instead of instances of
the derived class. Whether this would matter in practice is, of course,
a different question.
