Not sure I agree with the parent but thinking it through, you have a single connection and a cleaner life cycle. Streaming writes and reads could mean back-pressure is possible. A client can consume items as needed as opposed to mapping usage to a page size.

There's no worry about wasting a full request on the last page with a single item. In fact there's no worry about round trips at all, it's just a matter of buffer back pressure that communicates the need for more or less.

Hmm, when you think about it, its a pretty good way to go.
