It is an unnecessary restriction; nth neither needs self to be sized nor needs to be exempted from the trait object. It increases the utility of the nth method, because type specific implementations are available through `&mut I` or through an iterator trait object. It is a backwards compatible change due to the special cases of the `where Self: Sized` bound; it was already optional to include this bound in `Iterator` implementations.
