Article is missing a lot of keys points. With iterator you can chain them together to provide even higher level abstractions.
There are plenty of containers (new maps with different algorithms like a BtreeMap, linked lists, etc) that now with generics could also use a generic way of iterating over them.
There was a pre-proposal discussion that went into a lot of detail of what is possible that wasn’t intended the release notes. I highly suggest the writer of this article dig much deeper into more benefits of iterators than the two trivial options that were included in the experiment description.
