I was thinking about changing the return type even, to `KeyValueIterator<Windowed<K>, V>` since it is confusing to users about the key typed `Long` (Streams javadoc today did not explain it clearly either), note it is not backward compatible at all.
Personally I'd prefer to just deprecate the API and new new ones that return `KeyValueIterator<Windowed<K>, V>` directly, but if most people felt it is too intrusive for compatibility I can be convinced with `KeyValueIterator<Long, V>` as well.
