Returns an {@code ObjectSerializer} that mostly conforms to the strict JSON format defined in
<a href="http://docs.mongodb.org/manual/reference/mongodb-extended-json/">extended JSON</a>, but with a few differences to keep
compatibility with previous versions of the driver.  Clients should generally prefer {@code getStrict} in preference to this method.
