Should the documentation have an example for how to use multiple decoders?

In my implementation I need to use the default decoder for byte[] and GsonDecoder to map to objects and I'm doing the following in Java 11:

@Bean
    public Decoder decoder() {
        Decoder decoder = (response, type) -> {
            if (type.getTypeName().equals("java.lang.String") ||
                    type.getTypeName().equals("byte[]")
            ) {
                return new Decoder.Default().decode(response, type);
            } else {
                return new GsonDecoder().decode(response, type);
            }
        };
        return new ResponseEntityDecoder(decoder);
    }

Is this worth having an example in the documentation? I was inspired by this discussion https://github.com/spring-cloud/spring-cloud-netflix/issues/2246

Start by locating the existing decoder documentation and examples, then review how custom Decoder configuration is currently explained. Add an example covering separate handling for byte[] or String values and object decoding, and confirm the documentation clearly explains when the example applies.
