Amareshwari Sriramadasu commented on LENS-935:
----------------------------------------------
[~prongs], Do you think it is still required along with Estimate? If not,
Should we close it as Invalid?
> Add driver query acceptor

> After rewrite, the selection of driver is done just once. I propose the
> following:
> * Each driver has a list of acceptors
> * Once a driver is selected, it's asked "do you accept this query", which it
> answers using its acceptors
> * If the driver accepts, the flow after that is unchanged
> * If the driver rejects, that driver is removed from candidates, and
> selection happens again. Then the flow goes back to point 2.
> * If all reject, first driver's error is propagated.
