説明
Currently stream support is poor.
I'm doing experiments on my computer and under stream error nothing happens and this is totally dangerous.
Also I've noticed that code is dirty because first, need to handle callback of the requests, and later, handle the stream interaction (that could be a noop method, lol)
It could be more simple just handling the data as stream (Before my experienced creating fetch-timeline, I think that from2 is the right way, maybe JSONStream too) and, if a callback is provided, convert the stream into a callback interaction (for example, using read-all-stream).
This feature/refactor is very important to support filter/transform data with perfomance.
