Spring AbstractJacksonEncoder ignores FILTER_PROVIDER_HINT when encoding Flux<T>

WebFlux 7.0.0-M9: AbstractJacksonEncoder considers the FILTER_PROVIDER_HINT only when going through encodeValue(): https://github.com/spring-projects/spring-framework/blob/04492c3516f2c9882adbd55ae3fa6bafe513f8ef/spring-web/src/main/java/org/springframework/http/codec/AbstractJacksonEncoder.java#L224-L227 however when encoding a Flux<T> to a non-streaming media type, the hint is ignored.

The filter hint should probably be checked here: https://github.com/spring-projects/spring-framework/blob/04492c3516f2c9882adbd55ae3fa6bafe513f8ef/spring-web/src/main/java/org/springframework/http/codec/AbstractJacksonEncoder.java#L322-L334

Context: I was using MappingJacksonValue extensively to programmatically add Jackson filters to my responses and am replacing it now with using hints, where I noticed that they are not used for Flux<T> body types.

Side note: Some guidance on how to actually provide hints would be helpful. The only proper, user-facing API I found was the ServerResponse builder for functional endpoints. But I haven't found anything on how to provide hints for encoding client requests (WebClient) or responses returned from @RequestMapping controller methods.

My current solution is to replace the default JacksonJsonEncoder with a custom one:

class MyCustomEncoder extends JacksonJsonEncoder {

    MyCustomEncoder(JsonMapper jsonMapper) {
        super(jsonMapper);
    }

    @Override
    public Flux<DataBuffer> encode(Publisher<?> inputStream, DataBufferFactory bufferFactory, ResolvableType elementType, MimeType mimeType,
            Map<String, Object> hints) {
        return Flux.deferContextual(reactorContext -> {
            FilterProvider myFilter = ...; // Create configured FilterProvider from reactorContext
            Map<String, Object> hintsToUse = Hints.merge(hints, JacksonCodecSupport.FILTER_PROVIDER_HINT, myFilter);
            return super.encode(inputStream, bufferFactory, elementType, mimeType, hintsToUse);
        });
    }

    @Override
    public DataBuffer encodeValue(Object value, DataBufferFactory bufferFactory, ResolvableType valueType, MimeType mimeType,
            Map<String, Object> hints) {
        ContextView reactorContext = Context.empty();
        if (hints != null) {
            // thank you for putting the context in here 🙏
            reactorContext = (ContextView) hints.get(ContextView.class.getName(), Context.empty());
        }
        FilterProvider myFilter = ...; // Create configured FilterProvider from reactorContext
        Map<String, Object> hintsToUse = Hints.merge(hints, JacksonCodecSupport.FILTER_PROVIDER_HINT, myFilter);
        return super.encodeValue(value, bufferFactory, valueType, mimeType, hintsToUse);
    }

}
