Part of #1399 and #1469.
To allow an executor to reschedule a task when a future stops blocking, it is crucial that the future is attached to the same executor.
Currently, users are able to initialize a Future instance without supplying the executor parameter.
This behavior is necessary to allow calling client.call_async() before attaching the node to an executor (the future is attached to the running executor when processing the service response).
In asyncio, loop.create_future() was added to discourage users from initializing the Future class directly.
I suggest we follow the same path.
