Sorry for my confusing message here. I meant *this series* doesn't
attempt to use streams with filesystems (I wasn't considering raw block
in the same catagory as a traditional filesystems).

I am not abandoning follow on efforst to make use of these elsewhere. I
just don't want the open topics to distract from the less controversial
parts, and this series doesn't prevent or harm future innovations there,
so I think we're pretty well aligned up to this point.
