   At my company, we use Pulsar in an enterprise application that has requirements that my team cannot control. We cannot use "aggressive subscription/topic removal policies" as there are many other requirements that control those policies. We also cannot easily use Reader model as it is very hard to scale a Reader if you want to replicate a Consumer's "shared" subscription model, scaling so that multiple consumers on the subscription will share the load of messages. We cannot just re-code in Java, we are using Golang, which is why we need the feature in Golang client. 
   
   In our use case, Pulsar is processing a very large amount of data in throughput. It is important to us that if something goes wrong with our component where it is no longer able to listen/ack on its subscription, the subscription does not persist and cause a backlog of messages that could bring the enterprise level application down. Making our subscriptions non-durable seems like the perfect solution, but we can't use it because the Golang pulsar client doesn't support it.
