> There are a lot of extensions points both on the client and server sides. Most of these pluggable APIs are configurable but the configurations they receive are not the same.
> For example, Serializers, Deserializers, Partitioners, Assignors, QuotaCallbacks are passed config.originals(). On the other hand LoginModules, PrincipalBuilders and AuthenticationCallbackHandlers are passed config.values().
> In practice, having access to originals() is nice as it allows to use custom configurations by simply adding it to the client/server configuration.
