@amichel We have a feature request to add structured streaming support for Tibco EMS and JMS. Unfortunately, it's yet to be prioritized for the roadmap. 

I would request to file a feature request in our ideas portal https://ideas.databricks.com/ideas/, so that you can interact and receive the updates directly with PM team. The ideas portal allows the customers to submit enhancement ideas and other customers to vote on their submitted ideas, and also gives the customers a direct line of communication with PM. You can subscribe to status updates as well.
