Basically, it is for a sense of completeness. It feels weird that there is a way to check whether an iterable is a subset of a set or a superset of a set but no way to directly ask whether it is equivalent to the set.

Your request would be much more clear and easy to understand if you had started with concrete examples, especially since the terminology you are using is ambiguous.
