One of three constituents is used to provide the CollectionSerializer's #json_key: 1) the :root option - controlled by the caller 2) the #name of the first resource serializer - the root or underscored model name 3) the underscored #name of the resources object - generally equivalent to the underscored model name of #2 Of the three, only the latter 2 are out of the callers control, and only the latter two are expected to be singular by default. Not pluralizing the root gives the caller additional flexibility in defining the desired root, whether conventionally plural, unconventionally plural (e.g. objects_received:) or singular.
