While there may be a case for a "splitslices()" method on strings for text formatting purposes, that case is weaker for generic sequences - we don't offer general purpose equivalents to split() or partition() either. That said, the possibility of a sequence or container focused counterpart to "itertools" has come up before, and it's conceivable such an algorithm might find a home there.
