Makes sense.
In the meantime I looked at .NET API and discovered Topic Dispatch which would make (1) a lot easier to implement. But unfortunately we’re using mostly Java/Kotlin via JCSMP API which according to the documentation (PubSub+ Messaging API Developer Guide) doesn’t support Topic Dispatch. But in API Reference I found interface MessageDispatcher (Sorry, it looks like we sent you the wrong way.Let us guide you back.) so I have hope that it will be available soon
