I think the point is that this is the driver's problem, not the
applications. If you are using SQL level PREPARE/EXECUTE in your code
that's your problem, but if you are using an api like:
$stmt = $conn->prepare("SELECT * FROM tab WHERE x = ?");
$result = $stmt->execute(71);
Then the driver itself should know if the above query has been prepared
previously and further what type it has been prepared for so that it can
cast the 71 or prepare a new statement.
