In case of topic wildcards we loose topic details in a subscription PushStream, because it contains only payload.

Example:
subscribe to topic PUB/SENSORS/+/TEMP (single level wildcard is for sensor IDs). In this case, it's required to process payload with topic to map temp value to specific sensor ID.

You are right ... we will need a MQTTMessage type with a topic String and payload ByteBuffer for the PushStream. I will update the RFC as such
