I think this is a silly argument. It's much easier to write a database without query planner than with a query planner. The reason why you would want to have implicit language is because an optimal query might be different depending on what data you have and even what are you querying. For example if table has only 5 jorges it's probably better to use an index, but if majority of users are jorges or the table is very small it's far more efficient to just scan it.
