I don't think the DefaultServiceBusNamespaceProcessorFactory in the Service Bus SDK can use a shared ServiceBusClientBuilder. Is issue 37932 actually resolved?

Query/Question
My question is in reference to the following issue
#37932 .

In my shallow opinion it is still not possible to use a shared ServiceBusClientBuilder with the DefaultServiceBusNamespaceProcessorFactory. The doCreateProcessor() method constructs new ServiceBusSessionProcessorClientBuilderFactory instances on each call. The constructor chain then arrives at

AbstractServiceBusSubClientBuilderFactory(P properties, List<AzureServiceClientBuilderCustomizer<ServiceBusClientBuilder>> serviceClientBuilderCustomizers) {
        this((ServiceBusClientBuilder)null, properties, serviceClientBuilderCustomizers);

    protected AbstractServiceBusSubClientBuilderFactory(ServiceBusClientBuilder serviceBusClientBuilder, P properties, List<AzureServiceClientBuilderCustomizer<ServiceBusClientBuilder>> serviceBusClientBuilderCustomizers) {
        this.properties = properties;
        if (serviceBusClientBuilder != null) {
            this.serviceBusClientBuilder = serviceBusClientBuilder;
            this.shareServiceBusClientBuilder = true;
            this.serviceBusClientBuilderFactory = null;
        } else {
            this.serviceBusClientBuilderFactory = new ServiceBusClientBuilderFactory(properties);
            if (serviceBusClientBuilderCustomizers != null) {
                ServiceBusClientBuilderFactory var10001 = this.serviceBusClientBuilderFactory;
                Objects.requireNonNull(var10001);
                serviceBusClientBuilderCustomizers.forEach(var10001::addBuilderCustomizer);
            }

            this.serviceBusClientBuilder = null;
            this.shareServiceBusClientBuilder = false;
        }

    }

    }

which just sets this.serviceBusClientBuilder to null. Thus,

    protected ServiceBusClientBuilder getServiceBusClientBuilder() {
        if (this.serviceBusClientBuilder == null && this.serviceBusClientBuilderFactory != null) {
            this.serviceBusClientBuilder = (ServiceBusClientBuilder)this.serviceBusClientBuilderFactory.build();
        }

        return this.serviceBusClientBuilder;
    }

will create a new ServiceBusClientbuilder instance.

Since DefaultServiceBusNamespaceProcessorFactory is final, you cannot even inherit it to override doCreateProcessor() . What do you think? My objective is to use a shared ServiceBusClientBuilder in order to reduce the number of TCP connections established with ServiceBus. Since I am working with only one namespace, my application should be able to reuse a single TCP connection instead of creating one connection per Sender and per Receiver.

Why is this not a Bug or a feature Request?
The referenced issue is marked as completed, but I need clarification on why it is completed.

@moarychan could you confirm if indeed this was solved?
