Leftover follow-up commit for "1c8f47754241fea8b9c1463c08539ec31638a5de":

    * Use the "@JsonProperty()" annotation to serialize/deserialize
      objects that don't require any specialized processing.
      Use "@JsonSerialize" and "@JsonDeserialize" only for objects
      that need more specialized processing.

    * Remove FooSerializer JSON classes that are not used/needed anymore.

    * Update the implementation of remaining FooSerializer classes,
      and associated Foo classes.
