Why schedule Task instead of just returning Future?

[boc0]

First, thanks for making this.

Trying to await an indexing operation transport.py ensure_future()s the request so it's attached to its own loop. So the task cannot be started in my loop. Why not just return the future without ensure/create_task-ing it?

I believe the original intention was so that cancellation was easier? Not sure. Either way this won't be changing as we won't be implementing any breaking changes. See #81 for more information.
