Review comment:
> I am not sure. We can already do this via specifying the hints, and
the performance improvement doesn't look common enough to me.
As the platform becomes better and better, users' understanding of the
underlying service becomes less and less, it is difficult to control users'
behavior and we'd better to make the engine smarter and more applicable.
