Hi Rick,
I do not think that such interfaces are a good addition to the JDK,
we do not want to promote the fact that you can create a Stream from an Iterable because the resulting Stream is not efficient (or is not as efficient as it could be) and we can already uses a Supplier<Stream> if we want to to represent a factory of streams

See my comment on the bug for more details
